Operationalised DV and BOTH SIDES of the operationalised IV

18

Name the hypothesis

There will be a significantly faster reaction time (seconds) on a hazard perception test when participants drink 75cl of Red Bull compared to participants who drink 75cl of water.

A

directional

19

non direcational

22

24
Q

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

A

directional

25
Q

Previous research showed that there was no signidicant difference between those who ate a kitkat before the 100m sprint and those who did not eat a kitkat before running the 100m sprint
What type of hypothesis should you write?

A

A non directional
(because although there is previous research it doesnt state a direction)

26
Q

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

A

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.

27
Q

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

A

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
