• Exercise has a significant impact on blood plasma prolactin

• Exercise has no significant impact on blood plasma prolactin

True or false: Oranges are more expensive compared to apples.

• True, the average is higher (the bar graph)

• True, the error bars overlap, therefore, there is a significant difference.

• False, the error bars overlap, therefore there is NO significant difference. The variation is due to chance.

If both sets (set A and set B) have the same sample size/# of trials, then which set has a greater amount of variation within the data?

• Set A

• Set B

• Cannot tell without seeing the data table results were recorded in.

True or false: Cycle 2 significantly absorbed more copper compared to cycles 1 and 3.
