]]>When that has been completed the next step is to find the mean of the pre-test and the post test sores. In excel this can be done by selecting the auto sum icon and choosing average or in the function bar you type:=AVERAGE(the column where the score start: the column where the score end). After which you calculate the standard deviation. The Standard Deviation is a measure of how spread out the sores obtained by the participants are. When calculating the standard deviation using excel you type in: STDEV(B2:B10) in the function bar. In order to find the standard deviation without the excel you find the square root for the sum of each score subtracted by the mean score which is all squared then this is divided by the total number of scores. This information can be used to construct a comparative line graph or a bar chart.

The standard deviation and the mean can be used to tell how well the student did or how poorly. This is a result of how widespread the standard deviation is around the means or how tightly packed the standard deviation is around the means.
