| A | B |
|---|
| Z-score | Indicates the number of standard deviations a value lies away from the mean |
| Poisson | Counts the number of times an event occurs in a given interval |
| Frequency | The number of data entries in a class |
| Odds | The ratio of successes to failures |
| Simulation | Use a model to reproduce the conditions of a situation or process |
| Mutually Exclusive | Two events that cannot occur at the same time |
| Ogive | A line graph that displays the cumulative frequency of each class |
| Mean | The sum of the data entries divided by the number of entries |
| Statistic | Describes a sample characteristic |
| Event | One or more outcomes that is a subset of a sample space |
| Third | The quartile that is equivalent to the 75th percentile |
| Binomial | Only possible of two outcomes (success and failure) |
| Stratified | The population is separated into groups and a random sample is selected from each |
| Complement | The set of all outcomes in a sample space that is not included in a given event |
| Outlier | Any number that is 1.5 times the interquartile range below Q1 or beyond Q3 |
| Quantitative | Data that consists of numerical measurements or counts |
| Median | The middle data entry when the data is arranged in order |
| Descriptive | The branch of statistics dealing with organization, summarization, and display of data |
| Pareto | Used to show high importance by arranging the bars in descending order |
| Permutation | The order of events matters |
| Symmetric | In this distribution the mean, median, and mode are the same number |
| Ordinal | Data at this level can be arranged in order but differences between entries are not meaningful |
| Census | A count of the entire population |
| Parameter | Describes a population characteristic |
| Independent | The occurrence of the first event does not affect the probability of the occurrence of a second event |
| One | The total area under the normal curve |
| Geometric | Trial is repeated until success occurs |
| Qualitative | Data that consists of attributed, labels, or non-numerical entries |
| Pie | Used to show the relationship of parts to a whole |
| Left Skewed | A distribution where the mean is lowest, followed by the median and the mode |
| Cluster | One or more subgroups is selected and each number from that group is used |
| Empirical Rule | 68% of data lies within 1 SD, 95% within 2 SD, 99.7% within 3 SD |
| Standard Deviation | A measure of the typical amount an entry deviates from the mean |
| Systematic | Sample is selected from a population using regular intervals |
| Variance | Standard deviation squared |
| Scatter Plot | Ordered pairs are graphed to determine the relationship between two sets of data |
| Bias | The result of having a sample that is not representative of the population |
| Time Series | Used to show how data changes over equal intervals of time |
| Mode | The data entry that occurs with the greatest frequency |
