Effect = 40
Control
Correlation is...
A mutual relationship between variables
Find the median:
1,2,3,4,5,6,7,8,9,10

p = 0.5
this refers to...
Statistical insignificance
Determine which group has the smallest amount of variance.
Control SD = 0.82
Effect SD = 0.79
Effect
Statistical significance is...
The point of recognition (normally deemed via a p-value) that two datasets are statistically different.
The mean is...
10+20+30+40+50 / 5
30
p<0.01
This refers to...
Statistical significance
If error bars overlap this means that...
The data is likely to not be significantly different.
Certainty refers to...
The range of values presented in error bars demonstrating a possible (lack of) confidence in a data set's findings. OWTTE
The difference in means is...
110/50 - 60/30
0.2
With a confidence interval of 95% this means that...
The p-value point of significance is 0.05
What is the best for of variance for the mean?
Standard deviation
The confidence interval is...
the range of values that are accepted within a deemed 'norm' OWTTE
The IQR is...
1,2,3,4,5,16,17,18,19,20
18-3= 15
With a confidence interval of 1 standard deviation this means the p-value point of significance is...
0.32
