An investigator wanted to evaluate a weight loss program advertised on TV. She designed an experiment to measure results over time. She selected a group at random from among volunteers, measured their weight before starting the program, and then tracked them over time to determine any changes. This is a version of the paired differences approach but called randomized block design in ANOVA. We are controlling for individual differences by using the same individuals over time. Please do the analysis and show your results.
