| 7884024024 | Standard and variance deviation | Indicate the degree to which scores differ from each other and vary around the mean value for the set .Both show how much scores group together and how dispersed they are. | 52 | |
| 7884024025 | Variance | Determined by computing the difference between each value and the mean,squaring the difference between each value and the mean (to eliminate negative signs),summing the squares differences and then taking the average of the sum of squared differences. | 53 | |

| 7920652974 | Standard score or Z score | Standard scores enable psychologists to compare scores that are initially on different scales.For ex. A z score of 1 for 1Q test might equal 115,while a z score of 1 got the sat in mathematics might equal 600. | 57 | |
| 7920652975 | percentile score | Indicates the percentage of scores or below a particular score.Thus ,if you score at the 90th percentile,90 percent of the score are the same or below yours.Varys between 0.01 to 99.9. | 58 | |

| 7920652990 | If the correlation coefficient is +1 that perfect relationship is direct , as one variable increases,the other variable increases,and as one variable decreases,the other variable decreases. | 62 | ||
| 7920652991 | A correlation of 0 indicates no relationship at all between the two variables. | 63 | ||
| 7920652978 | Correlation coefficient are useful because they enabled psychologists to make predictions about Y when they know the value of X and the correlation coefficient | 64 | ||

| 7920652982 | negative correlation r= -1 | A slope that's going down | 68 | |
| 7920652983 | Interferential statistics | Are used to interpret data and draw conclusions.Use rules to evaluate the probability that a correlation or a difference between groups reflects a real relationship and not just the operation of chance factors on the particular sample that was chosen for study. | 69 | |
| 7920652992 | If the p value is less than 0.05 percent you a winner. | 70 | ||
| 7920652984 | Statistical significance | Is a measure of the likelihood that the difference between groups results from a real difference between the two groups rather than from chance alone. | 71 | |
| 7920652985 | Statistical significance ( p) | Cause of science not because of not by chance. | 72 | |
| 7920652993 | Some psychologists psychologists consider that results are significantly different only if the results have less than a 1 in 20 probability of being caused by a chance (p<.05) others consider thats results are significantly different only if the results have less that's a 1 in 100 probability of being caused by a chance. (p<.01) | 73 | ||
| 7920652986 | meta-analysis | Provides a way of statistically combining the results of individual research studies to reach an overall conclusion. | 74 | |
| 7920652987 | meta analysis | Analysis something that has been already analyzed it's a conclusion about the conclusion | 75 | |
| 7920652988 | Ethical guidelines | Debriefing,has to sign a consent form,you. An physically harm and mell or people | 76 | |
| 7920717350 | Correlation study | To prove what the experiment should go by on | 77 | |
| 7920717351 | Extraneous variables | confounding variables | 78 | |
