Topic |
My experiment is on evening caffeine consumption and deep sleep in young adults |
|
|
Quick summary |
I am looking at a group of young adults who will be consuming caffeine daily in the evenings and comparing their N3 sleep duration with a control group |
|
|
N3 Sleep |
The deepest stage of sleep |
|
|
Target population and why |
Is between 20 and 30 years old because N3 sleep decreases as people become older |
|
|
Acquiring sample |
I will use a random number generator to produce house numbers from cities on the islands then recruit people from 20 to 30 years old. |
|
|
Sample size |
My sample will consist of 52 islanders, 26 in each group |
|
|
How did I get sample size |
I used a power analysis calculator with a power of 0.8 and an alpha criterion of .05. I also consulted prior research that utilized EEG and hypnograms to measure sleep. In studies I looked at the groups ranged from 10-30 participants |
|
|
Random assignment |
I will use random assignment to assign participants into either the experiment or control group |
|
|
Experiment group |
Will receive 200mg of caffeine daily between 6-7pm and produce a daily hypnogram |
|
|
Control group |
Will produce a hypnogram once a day for the duration of the experiment |
|
|
Keeping track of data |
I will use the islands tasks menu to save participants graphs and Microsoft excel to track their exact daily N3 sleep times |
|
|
T-test |
The appropriate T-test for my data is an independent samples T-test because I have two groups and I am comparing their means |
|
|
Plot digitizer |
To get exact values from the hypnogram line graphs I will use a plot digitizer which is an online tool that lets me accurately measure data points on graphs |
|
|
To analyze my data |
I will use Jamovi to conduct a t-test with the data I have stored in Microsoft excel. |
