Hello, and thanks for helping me out.
I need to figure out what kind of test, if any, I can use to reject/
not reject a hypothesis.
The data concerns one individual at two different times. Thus the
data, I assume, is not independent.
The first set of data was obtained through observation of behaviors
outwardly expressed by an individual during sleep in standard
conditions. The second set of data was obtained through observation
again, but after the individual was placed on medication. Again, the
total amount of time over 7 nights a behavior was observed was divided
by the total amount of sleep over 7 nights to get a percent of how
much, on average, per night, an activity was performed.
What test can I run to see if there is a significant difference in the
amounts of each of the motions using only the averages (percentages)
and the total number of instances each behavior was observed over 7
nights.
I guess what I'm looking for is a test that can compare the
differences in averages only (thus there is no standard deviation to
use) but also take into account the number of instances that were used
to come up with the average to see if there's a significant
difference.
Thank you very much.
Here is an example of what I mean.
Data 1- Prior to Medication (cumulative 7 day data)
Instances Activity Time %
17 Not moving 6:56 65%
21 Kicking 1:41 16%
5 Snoring 0:38 6%
5 Switched Sides 0:23 4%
4 Rapid Breath 1:05 10%
Data 2- After Medication (cumulative 7 day data)
Instances Activity Time %
17 Not moving 6:29 77%
12 Kicking 0:36 7%
3 Snoring 0:38 7%
0 Switched Sides 0:00 0%
3 Rapid Breath 0:44 9%
