![]() The spread of values is evenly distributed around the mean and the median. The mean and the median are relatively close in value (mean = 53 and median = 54.5) indicating that the distribution of results are not significantly skewed to one end. These two values could be outlier values thereby give a false indication of the spread of the data. However the Range is limited by the fact that it only uses 2 values. ![]() This indicates how dispersed the data is, considering the test was scored out of 100. As can be seen from the data analysis table, the spread for history scores is from 7 to 100 – equating to a range of 93 marks.
