What type of study is a pre and post survey?
In summary, quasi-experimental design has been a common research method used for centuries. Pre-test and post-test design is a form of quasi-experimental research that allows for uncomplicated assessment of an intervention applied to a group of study participants.
Are people more honest on anonymous surveys?
You gain more honest feedback When a survey is anonymous, respondents are more inclined to discuss sensitive issues and provide more detailed and honest feedback. It’s why we tend to see more anonymous staff surveys, compared to those that require staff to provide identifiable information.
How can I statistically compare a pre and post test survey?
Join ResearchGate to ask questions, get input, and advance your work. If your groups come from separate samples, your test should be unpaired. If you want to use regression, the best way to compare the two samples is to create a dummy (0/1) variable that represents which group each respondent is in.
Can I do a dependent t-test if pre & post were anonymous?
Both surveys were run anonymously. It seems to me that dependent sample t-test follows a group of people, and then collects the results of the same people, knowing that person A scored 1 and then scored 2. Since my data is anonymous, I cannot really track this.
Can a paired t-test be used for pre and post surveys?
The paired t-test could only apply if you had some identity variable for matching so that you derive a ‘difference’ variable. As it stands, you may have to use two independent samples t- test with pre and post test sessions as the groups.
Which is the most robust non parametric test?
Calculate the Kolmogorov-Smirnov test with which you justify the use of parametric or non-parametric tests. Unless you have large departures for normality, the t-Test is relatively “robust” with regard to the this issue. In general, non-parametric tests would require you to have paired data, which you do not.
