MEASURES OF SPREAD (Part 1)
We have seen that measures of central tendency give us an
indication of where the center of the data is
Two sets of data, however, can have the same mean or
median but can be quite different if we look at the raw scores
MEASURES OF SPREAD (Part 2)
Quartiles and percentiles give us a picture of the dispersion of the
data around the median.
Quartiles and Interquartile Range
Quartiles divide a set of ordered data into four groups with
equal numbers of values
