Multiple rows per respondent

#1
Hey everyone,

I have 6 rows of data per respondent and I'd like to perform a linear regression analysis. I'm just not sure about 1 thing. My control variables have the same data for all 6 rows per respondent. Is this going to be a problem? I have 140 respondents, should I create 139 dummy variables to take into account that I have multiple observations for each respondent?

Thanks for any input in advance,

Gio

What is your study question that you want to answer? Will it deal with repeated measures?

You will probably need wide not long data, which would mean each ob would be in a new column.

My study question is to see how food product images affect purchase intent. My survey showed 3 food products to respondents, without and with an image. So 2 rows of observations per food product.
