A Statistic That Gives the "Center" or Average of a Distribution

Question

A statistic that gives the "center" or average of a distribution is known as the
A) mean.
B) mode.
C) deviation.
D) frequency.
E) X2 value.

Accepted Answer

The mean is a measure of central tendency that is calculated by adding up all the values in a distribution and dividing by the total number of values. It provides an estimate of the average value of the distribution and is commonly used as a summary statistic. The mode is the most frequently occurring value in the distribution, and while it can also be a useful measure, it may not necessarily represent the "center" of the data. The deviation is a measure of how spread out the data is, not a measure of central tendency. The frequency is a count of how often each value appears in the data, not a measure of central tendency. The X2 value is a statistic used in hypothesis testing, not a measure of central tendency.
