Suppose we did an experiment to gather data on the number of un-popped kernels of microwave popcorn. Half of the students in your class took home a bag, put it in the freezer overnight, and popped it the next day. The other half took the bag, left it on their kitchen counter overnight, and popped it the next day. Each group counted the number of un-popped kernels. Are these data paired or independent

Mira Hardy · Answer 1

This would be an example of independent data as the bags of popcorn were subjected to different conditions. In one case the bag was placed into the freezer, and in the second case it was left at room temperature. Considering that the conditions of both bags were different, we must view this data as independent.
