Recent advances in information technologies (IT) have powered the merger of online and offline retail channels into
Question:
Participants in the study were grouped into the following categories:
- Where_bought: Where they ended up purchasing an item: bought at the store, bought online.
- Who_bought: If they bought from the same or a different retailer.
Each participant was then measured on:
- Money: how much money they spent in dollars on the product.
- Time: how much time (in minutes) they spent looking at the product online.

3)What are the conditions in this experiment?
4)For each condition list the means, standard deviations, and standard error for the conditions for time and money spent. Please note that means you should have several sets of M, SD, and SE. Be sure you name the sets of means, sd, and se different things so you can use them later.
5)Which condition appears to have the best model fit using the mean as the model (i.e. smallest error) for time?
6)What are the df for each condition?
7)What is the confidence interval (95%) for the means?
8)Use the MOTE library to calculate the effect size for the difference between money spent for the following comparisons
9)What can you determine about the effect size in the experiment - is it small, medium or large?
10)How many people did we need in the study for each comparison?
