Question

If I approximated my response factor based on the average of two other response factors how will that change my quantitative results?

Answer 1

Each time an average amount of data is performed, there is an error of dispersion between the real value and the calculated average.

When you approximate a value, of two other values ​​that were calculated as means, there will be a slightly larger error in your result.

It depends on the study you do, it may or may not significantly affect your result. You must consider the percentage of acceptance that your study has to accept or reject an approximation by means.
