Answer 19

Non directional

Question 20

Question 24

There has been previous research that has shown that fanta improved running performance on a 100m sprint
What type of hypothesis would you write?

Answer 24

directional

Question 25

What type of hypothesis should you choose to write for the following…

There is previous research that was done that showed that there was no significant difference in results of those ppts who ate a kitkat before a 100m sprint and those who did not eat a kitkat before running the 100m sprint

Answer 25

A non directional
(because although there is previous research it doesnt state a direction - it shows no real results)

Question 26

Write a directional hypothesis for the following info
Redbull & No Redbull on 100m sprint in seconds

Answer 26

There will be quicker running times in seconds on those ppts who drank red bull compared to those ppts who did not drink red bull.

Question 27

Write a nondirectional hypothesis for the following
Redbull & No Redbull on 100m sprint in seconds

Answer 27

There will be a significant difference in running speed in seconds between those ppts that drink red bull compared to those ppts who do not drink red bull
