The median is frequently used in sophisticated statistics.

The presence of extremes can be an argument for using a median with interval level data.

In general, a univariate statistic is one in which

Measures of central tendency give us a standard point of reference when looking for differences between groups,

A mode is most useful when there are extremes in the data.

Which of the following occurs when determining a median with an even number of scores?

Measures of central tendency provide a description of a variable by focusing on a point.

It can sometimes be easier just to look at the data and locate the mean.

Measures of central tendency can only be used with single groups and cannot be used for comparison purposes.

A median can be used when

Measures of central tendency focus on the middle of the data.

One of the ways in which a mode is helpful is if
