Data handling means to collect
and present the data so that it
can be used in further studies and
to find some results. In this
chapter, we will study data
handling and its representation in
various forms.

R A N G E
To understand how the
observations are spread out, we
can look at the difference
between the highest and lowest
values. To find this difference, we
simply subtract the lowest value
from the highest value. This
difference is called the range of
the observations.

The mode of a set of observations is the observation that occurs
most often.

The median is the middle value when you arrange all the data in
order. Half of the values are higher than the median, and the
other half are lower than the median.
