When is it appropriate to use a histogram?
When data goes from least to most in order
Data should start from 0
Bars should be touching
IVs numerical (continuous)
Ordinal and ratio
What is a line graph?
These are graphs that show information thats connected in some way e.g. change in preformance on test overtime
Datas continouse
What is a pie chart?
Shows frequency data
Each slice shows the proportion of a category
Total pie is 100%
Used with nominal data
What is a scatter diagram
used when conducting correlation research
-When you have a paired numerical data and are trying to determine whether the two co-variables are related
-Scatter grams can be positive, negative or uncorrelated data at a glance
