They can also tell us how far a particular score is away from the mean. It tries go establish how a score is close to the mean or far away.Given a graph of normal distribution ,we can identify the difference by identifying a Z score by finding the difference between a graph.
for example the point in a disribution curve is 1.6 Then we can find the difference from the centre by subtracting 0.5 if its positive and use the difference to find the z score from the table......,continuing..a minute please please!!
