4. describes if a relationship exists between two variables, how strong this relationship is, and whether a change in one variable induces a positive or negative change in another
5. the difference between the upper and lower quartile values in a set of data
7. the average distance between each data point and the mean
8. a simple form of data visualization that consists of data points plotted as dots on a graph with an x- and y-axis
9. a type of data display that shows the relationship between two numerical variables
10. is the ratio of the rise to the run, or rise divided by the run
16. a measure of how dispersed the data is in relation to the mean
17. data compiled on an interval scale
18. is the ratio of the rise to the run, or rise divided by the run
19. when the curve appears distorted to the left or right in a statistical distribution
23. involves analyzing two separate variables and is used to determine whether or not two variables are related.
24. the value under which 25% of data points are found when they are arranged in increasing order
26. conforming to a standard; usual, typical, or expected

1. a measure that is used to find the difference between the observed value and the expected value of a variable.
2. is a statistical term that refers to the analysis of a single variable at a time.
3. a graphical representation of data that was collected from a sample or population
6. a point that usually has some symmetric placement with respect to points on a curve or in a solid

12. a graphical representation of discrete or continuous data.
13. the form of an object or its outline, outer boundary or outer surface
14. is the middle point in a dataset—half
15. consists of the smallest data value, the first quartile, the median, the third quartile, and the largest data value.
20. when the value of one variable or event increases or decreases as a result of the presence or lack of another variable or event
21. how spread scores are in a distribution out
22. a value in a data set that is very different from the other values
25. A general tendency among variables in a data set; usually between pairs of variables
