Quality cannot be controlled
What is meta analysis
Very large sample make it easier to generalise results
Many be variation in quality

What are line graph
Used to represent continuous data
Represent the chance if something over time
Scattergram
Have to be able to draw
Represent correctional data
Show relationship between to two variables
Line of best fit
