The mean is used for evenly spread data, and median for skewed data. Not sure when the mode should be used.

The mean is the average, the median is the middle, and the range is the difference between largest and smallest number. These terms are generally used in math.

It could be the mean or the median.

Mean is the average of a set of numbers. Median is the number in the middle when arranged in numeric oder. The mode is the most frequently used number in a set.

If the wide range is evenly spread between the very small and the very large (the distribution is symmetric) then there is not much to choose between the median and the mean. If not, the median will have some advantages as a measure of central tendency.

The mode is the only one of these measure which can be used with qualitative data: the mean or median are impossible to compute. Also, for a data set consisting of a relatively small number of observations of a discrete variable the mode or modal class is the easiest to find.

Neither.

The median is used when reporting ordinal data.

Excel has a function called MEDIAN which can be used. Usually you would put the cell range within it as follows: =MEDIAN(A1:A15)

The mean.

steam and leaf plots are used to get the range, median, and mode of a group of numbers.
