Can be used to represent single statistics
Multiple data sets can be shown and compared
Scattergrams
To show correlation/relationship
Line of best fit indicates relationship
Used to show type and strength of correlation

Calculating the range
Range
Subtracting the lowest score from the highest
Standard deviation
The measure of the spread of scores around the mean
What three thing must you do in the sign test
Be looking for a difference
Have used repeated measures experimental design
Have data that is organised into categories
The accepted level of probability is
0.05 meaning that the researcher will accept the hypothesis
Your calculated critical value needs to be
Equal to or less than the table value to be deemed as significant
