I have data on sales and various marketing efforts, such as advertising spend, social media engagement, and promotional activities. How can I use regression to quantify the effectiveness of these marketing strategies on sales?
It's as easy as it can be on Spss. First you have to enter your quantitative data into Spss. Identify your variables in the variables view. In the data view, you transform the measures of your Marketing strategies into composite variables. Also transform your sales variable into a composite variable.
Then, click on analyze >>regression >> linear. Drag your independent variables (marketing strategies) into the independent variables box. Drag your dependent variable (sales) into the dependent variable box. Then click okay.
Your multiple regression output will come out showing the relationship between your variables as well as the effects of each of your marketing strategies on the dependent variable - - sales.
You can send me a direct message here for more clarity. I might have not been so detailed in this answer.
