I want to compare the job satisfaction of two groups with a two-sided t-test. My hypothesis is that the mean of group B is higher than the mean of group A
This are the results of my calculations:
- Group A: mean = 3.79, SD = 0.99
- Group B: mean = 4.07, SD = 0.90
t-value: -2.67** p-value= 0.0079**
I've used a the following code in R for the t-test
My question: How do I have to describe/interpret this result in correct terms for an academic paper?
(Do I have to use a one-sided-test? I am not sure, since my arguments for my hypothesis are kind of bad)
