Across
- 3. sum of squared deviations from the mean, divided by the count minus 1
- 4. if the two halves on either side of the center look approximately like mirror images of each other
- 6. has more than two modes
- 9. the distribution of a quantitative variable slices up all the possible value of the variable into equal width bins and gives the number of values falling into each bin
- 12. look for: single vs multiple modes; symmetry vs skewness; outliers and gaps
- 15. the difference between the first and third quartiles
- 18. average
- 19. a distribution that's roughly flat
- 20. the place in the distribution of a variable that you'd point to if you wanted to attempt the impossible by summarizing the entire distribution with a single number
- 21. value approximately equal to 1/4 of the data
- 25. a distribution that's not symmetric and one tail stretches out farther than the other
- 26. extreme values
Down
- 1. has two modes
- 2. a calculated summary that is not affected by outliers
- 4. shows quantitative data values in a way that sketches the distribution of the data
- 5. reports the minimum value, Q1, the median, Q3, and the maximum value
- 7. parts of the distribution that typically trail off on either side
- 8. uses adjacent bars to show the distribution of a quantitative variable
- 10. a region of the distribution where there are no values
- 11. a dot for each case against a single axis
- 13. the square root of the variance
- 14. the ith percentile is the number that falls above the i% of the data
- 16. difference between the lowest and highest values
- 17. a numerical summary of how tightly the values are clustered around the center
- 22. having one mode
- 23. a hump or local high point in the shape of the distribution of a variable
- 24. the middle value
