I'm doing research about The changes in dietary habits among undergraduate students before and during COVID-19. My research objective is to determine dietary habits before and during COVID-19. I want to know if there are possible changes between the two periods. Does anyone know how to determine this using logistic regression in SPSS?
Several things: 1 multivariate means more than one DV. 2. Your question: add a 0,1 dummy as an IV in your regression. Let 0 be pre and post period be 1. If this new regression coefficient is significantly different from zero then there's a difference.between the two periods. Best wishes, David Booth
Hello Hayatun Syamilah,
First, you have to make two different datasets for before and after COVID. Then make dummy variables in the respective dataset with "before COVID" coded as 0 and "after COVID" coded as 1. After that, you can merge (variable merge) these two datasets and perform logistic regression. Thank you!
To do this, you can use regression analysis with dummy variable. To do this, the dietary habits among undergraduate students are first placed in a column and below. Then, a dummy variable is defined that has a value of 1 for before COVID-19 and zero for during COVID-19. We now have two columns, one for dietary habits among undergraduate students (Dependent variable) and the other for a dummy variable with values of zero and one (Independent variable).
Hope the above points are useful for you. Good Luck
