Algebra Unit 10

1. A measure of how spread out data values are from the mean.
5. The difference between the upper and lower quartiles.
7. A distribution with a long tail extending to the left; most data values are on the higher end.
11. A graph that uses points to show the relationship between two numerical variables.
14. The average of a set of data values; found by adding all values and dividing by the number of values.
16. (Q3): The median of the upper half of an ordered data set.
19. A relationship in which one variable tends to decrease as the other increases.
20. A symmetric, bell-shaped distribution centered around the mean.
21. The difference between the maximum and minimum values.
22. The smallest value in a data set.

2. A table that displays the relationship between two categorical variables.
3. A distribution with a long tail extending to the right; most data values are on the lower end.
4. A situation in which there is no apparent association between two variables.
6. The proportion or percentage of observations in a category.
8. A relationship in which one variable tends to increase as the other increases.
9. (MAD): The average distance of each data value from the mean.
10. A graph that displays the five-number summary (minimum, Q1, median, Q3, maximum) of a data set.
12. (Q1): The median of the lower half of an ordered data set.
13. The square of the standard deviation.
14. The value or values that occur most frequently in a data set.
15. The middle value in an ordered data set. If there are two middle values, the median is their average.
17. The largest value in a data set.
18. A graph that uses bars to show the frequency of data within intervals.
