2. shape that is stretched out in either the positive or negative direction
4. using a line to summarize the relationship in the data on a scatterplot
5. total of all the amounts, divided by, how many amounts there were
8. describes the variability of a data set, that is, how the data varies from the mean
12. found using medians to divide a data set into quarters
14. data represented numerically, including anything that can be counted, measured, or given a numerical value
16. shape that when reflected across the mean, the display is roughly the same
18. measure of how well a line fits an individual data point
20. data categories including characteristics, for example, names, ages, occupations, etc
21. measures that describe a data set by identifying the middlemost value by a single number, usually described as averages
22. whole set of individuals, items or data from which a statistical sample is drawn
23. strength of a relationship between two variables

1. in a set of scores, values or numbers, the one that occurs the most
2. measure of how much individual scores in a data set differ from the mean
3. type of graphic display using dots and a simple scale to compare the counts within categories or groups
6. graph using bars to represent frequency distribution where, bar heights represent the score frequencies and there are no spaces between the bars
7. number of times a particular event or item appears in a set of data
8. method of collecting a sample of data by asking people questions
9. type of average which is the middle value of an ordered set of data values
10. when a study systematically produces results that misrepresent a population
11. collection of information gathered by observation, questioning, or measurement
13. section of a whole group
15. branch of mathematics dealing with collection, analysis, interpretation, and presentation of data
17. diagram where points are plotted to show the relationship between two variables
19. a value far away from most of the rest in a set of data
