6216142564Civil RightsThe rights of citizens to political and social freedom and equality.0
6216153678Fourteenth AmendmentA constitutional amendment which defines citizenship and expressly forbids the restriction of rights of citizens.1
6216166315Equal Protection of the LawA right guaranteed to all persons. Essentially, the law applies the same to everyone unless otherwise specified, and such specifications cannot be made without reason and cannot violate equality. For example, laws regarding abortion only directly apply to people who can bare children.2
6216198060Thirteenth AmendmentA constitutional amendment which bans slavery and all involuntary servitude, except in cases as punishment for crimes duly convicted.3
6216206110Civil Rights Act of 1964Under President Lyndon Johnson's Great Society, this act banned segregation by race in public and job discrimination based on race, sex, religion, and national origin.4
6216217020SuffrageThe right to vote.5
6216222064Fifteenth AmendmentA constitutional amendment stating that suffrage cannot be "denied or abridged" based on race, color, or previously being in servitude.6
6216237644Poll TaxesTaxes necessary to register to vote. These were used by some states, especially southern states, after the ratification of the Fifteenth Amendment to restrict black male suffrage, but were expressly made illegal by the Twenty-fourth Amendment.7
6216262627White PrimariesPrimary elections in some southern states, especially for the Democratic Party, open only to white voters.8
6216270087Twenty-fourth AmendmentA constitutional amendment which declares poll taxes illegal.9
6216274707Voting Rights Act of 1965An act under the Great Society which attempted to prevent local and state barriers against African-Americans voting.10
6216286220Equal Rights AmendmentAn amendment written in 1923 and attempted again to be passed in the 1970s guaranteeing women equal civil rights. It was never passed.11
6216297322Americans with Disabilities ActA 1990 labor law prohibiting "unjustified discrimination based on disability."12
6216303969Affirmative ActionPolicies favoring those who are discriminated against. For example, in Regents of the University of California v. Bakke, Bakke claimed that the affirmative action policy quota for minorities at the college was unfair to him.13
6216319876Scott v. SandfordAn 1857 Supreme Court case in which a man, Dred Scott, tried to claim freedom on the basis that his master had taken him into free territory. The Court ruled that not only was he still legally in bondage, black people could not be citizens so he had no right to sue in the first place.14
6216332030Plessy v. FergusonAn 1896 Supreme Court case in which a man, Plessy, refused to move from the 'whites only" car on a train due to being only 1/16 African-American, but was arrested. The Court ruled that segregation based on race was constitutional as long as facilities were equal.15
6216351026Brown v. Board of EducationA 1954 Supreme Court case in which the Court ruled that 'separate but equal,' the general policy established by Plessy, was inherently unequal, ending public school segregation.16
6216364444Hernandez v. TexasA 1954 Supreme Court case in which a man, Hernandez, was indicted and sentenced for the murder of another man before an all-white jury. Because Mexican-Americans had not served on a jury in the county for 25 years, and their populations were not small enough to warrant this, Hernandez argued that his jury had not been fair. The Court unanimously ruled in his favor, setting the precedent that Mexican-Americans should receive the same protection under the 14th Amendment.17
6216406348Korematsu v. United StatesA 1944 Supreme Court case in which Korematsu, a man of Japanese descent, violated Executive Order 9066 and local statutes by remaining in an area of California deemed unfit for Japanese-Americans to stay in due to the suspected threat of espionage. The Court ruled that the exclusion would not be constitutional during normal times, but that war powers were invoked so the actions were within the government's boundaries.18
6216451648Reed v. ReedA 1971 Supreme Court case in which a separated couple's adopted son died, and the father was named in charge of his estate because a state law held that males be given higher preference. The Court ruled that this was a violation of the Equal Protection Clause of the 14th Amendment, and that merit must be used instead.19
6216473904Craig v. BorenA 1976 Supreme Court case in which an Oklahoma law prohibited selling a certain type of low-level alcohol beer to males under age 21 and females under age 18. The Court ruled that the law was discriminatory.20
6216498963Regents of University of California v. BakkeA 1977 Supreme Court case in which a white man was denied admission to a medical school because they had to fill a quota for minorities, who he claimed he was more qualified than. The Court ruled in favor of Bakke, though it was established that race could be used an an equally weighted criterion.,21
6216538972Probable CauseThe standard needed for police to search cars, homes, etc. and/or seize property.22

6216570494Establishment ClausePart of the First Amendment which prohibits Congress from establishing official religion.25
6216577667Free Exercise ClausePart of the First Amendment which prohibits Congress from prohibiting the free exercise of religion.26

6216611427PenumbrasThe implied rights of a constitution and meanings of a law.28
6216629334Griswold v. ConnecticutA 1965 Supreme Court case in which medical professionals were convicted of violating a Connecticut law that prohibited health care professionals from discussing birth control with married patients for the purposes of preventing conception. The Court determined that the right to privacy, while not specifically enumerated in the Constitution, was created by the penumbras of the 1st, 3rd, 4th, and 9th Amendments.29
6216663283Mapp v. OhioA 1961 Supreme Court case in which a woman's home was searched for a criminal, but police officers found obscene materials, for the possession of which she was convicted. The Court ruled that illegally seized evidence cannot be used in a criminal trial.30

5921716901Extreme Value TheoremIf f is continuous on [a,b] then f has an absolute maximum and an absolute minimum on [a,b]. The global extrema occur at critical points in the interval or at endpoints of the interval.12
5921716902Critical NumberIf f'(c)=0 or does not exist, and c is in the domain of f, then c is a critical number. (Derivative is 0 or undefined)13
5921716904Mean Value Theorem for DerivativesThe instantaneous rate of change will equal the mean rate of change somewhere in the interval. Or, the tangent line will be parallel to the secant line.14

6072909971Statistica calculated value about a population from a sample(s).2
6072909972Medianthe middle point of the data (50th percentile) when the data is in numerical order.3
6072909973Variabilityallows statisticians to distinguish between usual and unusual occurrences.4

6072909975Skewed Rightmean is a larger value than the median.6
6072909976Z-score/T-scoreis a standardized score. This tells you how many standard deviations from the mean an observation is.7
6072909977Normal Modelis a bell shaped and symmetrical curve. As σ increases the curve flattens. As σ decreases the curve thins.8
6072909978Mutually ExclusiveA and B have no intersection. They cannot happen at the same time.9
6072909979Independentif knowing one event does not change the outcome of another.10
6072909980Law of Large Numbersas an experiment is repeated the experimental probability gets closer and closer to the true (theoretical) probability.11
6072909981Correlation Coefficient (r)is a quantitative assessment of the strength and direction of a linear relationship. between -1 and 1.12
6072909982Least Squares Regression Line (LSRL)is a line of mathematical best fit. Minimizes the deviations (residuals) from the line. Used with bivariate data.13
6072909983Residual (error)is vertical difference of a point from the LSRL. They should all add to zero. Is the difference between the observed and expected value.14
6072909984Coefficient of Determination (r-squared)gives the proportion of variation in y (response) that is explained by the relationship of (x, y).15
6072909985ExtrapolationLRSL cannot be used to find values outside of the range of the original data.16
6072909986Influential Pointsare points that if removed significantly change the LSRL.17
6072909987Censusa complete count of the population. Disadvantages of this: Not accurate, Expensive, Impossible to do18
6072909988Simple Random Sampleone chooses so that each unit has an equal chance and every set of units has an equal chance of being selected.19
6072909989Stratified Samplingdivide the population into homogeneous groups then SRS from every group. [Observational studies]20
6072909990Cluster SamplingUsually can be based on location. Select a random location and sample ALL at that location. Divide the population into heterogeneous groups and SRS a certain amount of groups. Take all members/things in that group.21
6072909991Biasfavors a certain outcome, has to do with center of sampling distributions - if centered over true parameter then considered unbiased22
6072909992Voluntary Response Biaspeople choose themselves to participate.23

6072909998Double Blindneither the subjects nor the evaluators know which treatment is being given.29
6072909999ReplicationA MUST for EVERY experimental design. Uses many subjects to quantify the natural variation in the response.30
6072910000Completely Randomized Designall units are allocated to all of the treatments randomly [Experiment]31
6072910001Randomized Blockunits are separated based on a KNOWN factor. Then randomly assign treatments in each group -reduces variation32
6072910002Matched-Pair DesignOnce a pair receives a certain treatment, then the other pair automatically receives the second treatment. OR individuals do both treatments in random order (before/after or pretest/post-test) Assignment is dependent33
6072910003Confounding Variablesare where the effect of the variable on the response cannot be separated from the effects of the factor being tested - happens in observational studies - when you use random assignment to treatments you do NOT have this!34
6072910004Randomizationreduces bias by spreading extraneous variables to all groups in the experiment. MUST have in EVERY experiment35
6072910005Binomial ProbabilityTrials have two outcomes; Trials are independent; and most importantly, the number of trials are fixed!36
6072910006Geometric Probabilitytwo mutually exclusive outcomes, each trial is independent, probability (p) of success is the same for all trials. (NOT a fixed number of trials)37

6072910009Central Limit Theoremwhen n is sufficiently large (n > 30) the sampLING distribution is approximately normal even if the population distribution is not normal.39
6072910024Lurking Variableis a variable that is not included as an explanatory or response variable in the analysis but can affect the interpretation of relationships between variables. It can falsely identify a strong relationship between variables or it can hide the true relationship.40
6072910026Simulationis a way to model random events, such that simulated outcomes closely match real-world outcomes41
6072910027Placebo effectA remarkable phenomenon in which a fake treatment, can sometimes improve a patient's condition simply because the person has the expectation that it will be helpful42
6072910029HistogramA graphical display that represents a frequency distribution by means of rectangles whose widths represent class intervals or "bins"43
6076074473Interquartile RangeA numerical description of a distribution requires both a measure of center and a measure of spread44
6076095619"X bar"Sample mean45
607611218768-95-99.7 rulepercentage of data within 1, 2, and 3 standard deviations of a normally distributed dataset.46
