Lab 10 Homework
A sample of 50 residential substance abuse clients are enrolled in your mindfulness
Program designed to address depression. Self-rating depression scales were
measured before the clients entered the program and then again after program
completion (with higher scores representing higher levels of depression).When
you entered your data, pre-test scores was input as Variable 1 and post-test scores
were input as Variable 2.Below is the SPSS output.
1. Based on your degrees of freedom, what is your critical-t?
2. What is your p-value?
p-value is the sig(2-tailed) value, 0.175
3. What is your SD?
4. Did you reject or retain H0?
Retained H0 since the p-value is greater than 0.05
5. Interpret your results.Include an explanation of the p-value and confidence
statistically, there is no significant difference between the means of variable 1 and variable 2 because the sig(2-tailed) value(which is the p-value) is greater than 0.05.
also, since the confidence interval includes zero between it then statistically there is no significant difference between means of variables 1 and 2.
