Across
- 1. Each value in a categorical data set is an individual category from a set of categories. Categorical data values are not quantities or measurements. (Lesson 1)
- 6. A data value that is much greater or much less than the rest of the data values (Lesson 16)
- 7. A measure of spread given by the difference between the third quartile and the first quartile (Lesson 13)
- 9. A question that can be answered by collecting data values that can vary (Lesson 1)
- 10. A data value that is collected from a person, an animal, or an object being studied (Lesson 2)
- 14. A histogram that is constructed by using relative frequencies rather than frequencies to determine the heights of the bars (Lesson 5)
- 16. For an ordered numerical data set, quartiles are the three numbers that divide the data set into quarters. The first quartile is the median of the lower half of the data set. The second quartile is the median. The third quartile is the median of the upper half of the data set. (Lesson 13)
- 18. Summarizes a data distribution. The table includes the data values, which are sometimes grouped into intervals, and the frequencies of those data values. (Lesson 3)
Down
- 2. A summary of a data set that describes what values are in the data set and how often each data value occurs (Lesson 2)
- 3. A graphical representation of the five-number summary. This summary consists of the minimum value, first quartile, median, third quartile, and maximum value. (Lesson 14)
- 4. The extent to which data values in a data set differ from each other. Variability occurs when the data values are not all the same. (Lesson 9)
- 5. Each value in a numerical data set is a number that could represent a quantity or measurement. Numerical data values often have units. (Lesson 1)
- 8. The fraction of data values that are included in an interval or category. To find the relative frequency of an interval or category, divide the number of data values in it by the total number of values in the data set. (Lesson 5)
- 11. A plot of numerical data values along a number line. Each data value is represented by a dot placed in a column directly above the corresponding number on the number line. (Lesson 2)
- 12. A measure of center appropriate for numerical data distributions that are symmetric or approximately symmetric. It is the average of the values in the data set. (Lesson 7)
- 13. A graphical representation of a numerical data set that has been grouped into intervals. The number of observations in each interval is represented by a bar drawn above that interval on a number line. The height of the bar represents the frequency. (Lesson 4)
- 15. A measure of spread given by the difference between the maximum value and minimum value in a data set (Lesson 2)
- 17. A measure of center appropriate for numerical data distributions that are skewed. To find the median, the data values must be ordered from least to greatest. For an ordered data set with an odd number of values, the median is the middle value. For an ordered data set with an even number of values, the median is the average of the two middle values.
