Being able to see the variability in a study

Difference study: means and Standard deviation

Probability and confidant they are different.

What is biologically or clinically significant?

Has a meaningful impact

Does the result make a difference in respect to the situation

Define in your own words the concept of the mean?

Overall average, showing the central tendency of the data

Define in your own words the concept of the Standard Deviation?

A measure of the variability around the central tendency

Stand error vs Standard Deviation

S.E.- distribution of how means compare

S.D. distribution of how means are individual standards points compare

Interpreting data (graphs and tables)

Differences versus associations?

Differences between groups/ treatments compares means and variability between groups.

(ex. Pre vs post exercise, Group A vs Group B)

Associations: see how one variable relates to the other. See correlation between variables.

What is statistically significant?

Being able to see the variability in a study

Difference study: means and Standard deviation

Associations: if the data is very comparable and it inter-laps each other.

Properties of means and standard deviation it doesn't cant about how different the

averages are

Probability and confidant they are different.

What is biologically or clinically significant?

Has a meaningful impact

Does the result make a difference in respect to the situation

If there is a overlap its okay

Is the difference meaningful

Depends on the situation and the group.

Can use means to figure out

(i.e. stroke patients gaining on VO2 is amazing compared to gaining 1 in an athlete not a

big difference)
