Across
- 2. The systematic error that occurs when individuals chosen for a subset do not participate, and their reasons for not participating are related to the characteristics being studied
- 8. The value that divides a data set into two equal halves when the data is ordered.
- 9. A characteristic that describes a whole group of interest.
- 10. The extent to which data points are spread out or clustered together around a central value.
- 11. A tabulation showing how often each different value in a set of data occurs.
- 12. A smaller group selected from a larger whole to represent its characteristics.
- 14. The value that appears most often within a data set.
- 15. A numerical measure calculated from data obtained from a portion of a larger group.
- 16. The entire collection of elements about which a researcher wants to gain insight.
Down
- 1. A range of values that is likely to contain a population parameter with a certain degree of probability.
- 3. A measure of the amount of variation or scattering of a set of values. It is the square root of the variance.
- 4. The number of units or observations included in a study.
- 5. The principle that states that as the size of a random subset increases, the distribution of its average will approximate a normal shape, regardless of the original distribution's form.
- 6. A measure that indicates the typical or most common value in a data set. Examples include the arithmetic average, the middle value, and the most frequent value.
- 7. A theoretical probability that describes the possible values of a summary measure calculated from numerous random subsets of the same size taken from a particular whole and the likelihood of each value.
- 13. The sum of all values divided by the total number of values; a common measure of central tendency.
