For my Honours dissertation I am using a 2x2 experimental design with four treatments. I have conducted a pre-test survey on Qualtrics to test the images which I will use for the four treatments in the main study, and respondents were randomly allocated to one of the four conditions.



I am measuring the sustainability and aesthetic design of delivery packaging and I want to check the images are having the intended effect using a one-sample t-test on each condition to see if there was a significant difference in the perceived sustainability and aesthetic design of the delivery packaging from the neutral value (4) for EACH experimental condition.



I have exported my data from Qualtrics to show the randomisation but how can I now analyse the measures for the the different randomised groups?



Thanks in advance!
