This graph shows that Victor’s data has a negative skew as shown by the long tail on the left. This means that the modal score was higher than the median and the mean and suggests that the majority of prisoners had relatively high levels of paranoia of around 75%.
|Some identified negative skew and explained it well relating to mode, median and mean.||Lots of people said positive when the skew was negative|
|Good use of the actual data, looking at the peak of the graph (mode) and dropping a line down onto the x axis to find the most commonly occurring paranoia score.||Some did not mention positive or negative skew|
|Some didn’t realise that it was a skew graph|
