Across
- 5. A value that divides ordered data into four equal parts.
- 6. Measure of a distribution’s asymmetry (right = positive, left = negative)
- 9. The middle value in an ordered list (or average of two middle values).
- 10. Difference between the third and first quartiles.
- 12. A measure of how spread out values are around the mean;
- 14. Value below which a given percent of observations fall.
- 16. Smooth curve representing a continuous distribution (area = 1).
- 17. An observation unusually far from the rest of the data.
- 19. Difference between the maximum and minimum values.
- 20. Minimum, Q1, median, Q3, and maximum.
Down
- 1. Symmetric bell-shaped distribution defined by mean and standard deviation.
- 2. The value that appears most frequently.
- 3. Average squared distance of values from the mean.
- 4. shape of curve with high measure of spread
- 6. measures of (blank) Statistics that describe how much the data vary
- 7. shape of curve with low measure of spread
- 8. measures of (blank) Statistics that describe a typical or central value of a dataset.
- 11. Distribution for variables that can take any value in an interval.
- 13. Distribution for countable outcomes with assigned probabilities.
- 15. Approximate percentages within 1, 2, and 3 standard deviations for normal data (68–95–99.7).
- 18. The arithmetic average of a set of numbers.
