Across
- 2. aka MAD; the average of the distance each value is from the mean of the data set
- 3. The distance between a value from the data set and the mean of the data set.
- 5. The number of data values included in each interval displayed in a frequency table or histogram
- 7. The number in the exact middle of a data set after the numbers are in order from least to greatest
- 9. Range aka IQR; A measure of variability for skewed data distributions that describes how spread
- 10. The average value of a group of numbers; put the numbers in order from least to greatest, add up the values, and divide by how many numbers are in the set.
- 11. the middle 50 percent of the data are; subtract the lower quartile from the upper quartile
- 12. Occurs when the observations in a data set are not all the same
- 13. A question that can be answered by collecting data and that anticipates variability in the data collected; you can have different correct answers to this question
- 15. The number of data values included in each interval divided by the total number of values in the data set
- 16. Data that can be represented as a group or category (i.e. hair color or flavor of ice cream)
Down
- 1. aka Q1; The median of the bottom half of the values in a data set
- 4. Data that can be represented as numbers (i.e. age or number of pencils)
- 6. The median of the top half of the values in a data set
- 7. The value that occurs most often in a data set
- 8. A collection of numbers, values, or categorical data often gathered to answer a particular statistical question
- 14. A set of numbers that lie between two specific values and include the lower of the two values but not the upper one. The upper value belongs to the next interval
