| 2567914917 | Statistics | Is the science of collecting, organizing, summarizing, and analyzing information to draw conclusions or answer questions. In addition, statistics is about providing a measure of confidence in any conclusions | 0 | |
| 2567920766 | Population | The entire group to be studied | 1 | |
| 2567920767 | Individual | Is a person or object that is a member of the population being studied | 2 | |
| 2567922051 | Sample | A sample is a subset of the population that is being studied. | 3 | |
| 2567924767 | Statistic | A numerical summary of a sample | 4 | |
| 2567978757 | Descriptive Statistics | Consist of organizing and summarizing data. Describe data through numerical summaries, tables, and graphs. | 5 | |
| 2567984987 | Inferential Statistics | Uses methods that take a result from a sample, extend it to the population, and measure the reliability of the result. | 6 | |
| 2567989250 | Parameter | Is a numerical summary of a population. | 7 | |
| 2567993068 | Qualitative | Allow for classification of individuals based on some attribute or characteristic. | 8 | |
| 2567994877 | Categorical | Allow for classification of individuals based on some attribute or characteristic. | 9 | |
| 2567996763 | Variables | Allow for classification of individuals based on some attribute or characteristic. | 10 | |
| 2567996818 | Quantitative Variables | Provide numerical measures of individuals. The values of a quantitative variable can be added or subtracted and provide meaningful results. | 11 | |
| 2568016665 | Discrete variable | Is a quantitative variable that has either a finite number of possible values or a countable number of possible values. | 12 | |
| 2568029491 | Continuous Variable | Is a quantitative variable that has an infinite number of possible values that are NOT countable. | 13 | |
| 2570823692 | A variable is at the nominal level of measurement | If the values of the variable name, label, or categorize. In addition, the naming scheme does not allow for the values of the variable to be arranged in a ranked or specific order. | 14 | |
| 2570830999 | A variable is at the ordinal level of measurement | if it has the properties of the nominal level of measurement, however the naming scheme allows for the values of the variable to be arranged in a ranked or specific order. | 15 | |
| 2570834473 | A variable is at the interval level of measurement | if it has the properties of the ordinal level of measurement and the differences in the values of the carible have meaning. | 16 | |
| 2570837160 | A variable is at the ratio level of measurement | if it has the properties of the interval level of measurement and the ratios of the values of the variable have meaning. Arithmetic operations such as multiplication and division can be performed on the values of the variable. | 17 |
