When comparing large data sets.

Suppose you plotted the same pairs of variables from two data sets on the same scattter plot, perhaps representing the two data sets in distinct colours. Then if the data sets differed sufficiently in standard deviation you would notice greater scatter or spread in one of them.

The Count Function can only be used with numeric data. true or false

It is possible for two sets of data - not ALL of which are the same - to have the same measures of central tendency. However, if the two sets do have a mode, then that number must appear in both sets ... several times.

Organizing the data into a frequency distribution can make patterns within the data more evident.

No, because sometimes sets of data can have different numbers and other sets of data can have modes in them.

No, not all data sets have a mode but all data sets have a mean and median.

A recursive function can only call itself, as it is not open to other connections. A reentrant function can connect to several data sets simultaneously.
