Answer:-

Given That:-

Imagine that a group of obese children is recruited for a study in which their weight is measured, then they participate for 3 months in a program that encourages them to be more active, and finally their weight is measured again.

Explain how each of the following might affect the results:?

regression to the mean:-

Regression to the mean occurs when the second measurements of a particular variable are less extreme than the first. If obese children who are quite active selected to participate in the study, improvements at the end of the program might be due to regression toward the mean and not the program's effectiveness.

spontaneous remission:-

Spontaneous remission refers is an unexpected improvement from a condition that usually progresses. Internal physiological factors may naturally lead to a decline in obesity among the study's participants.

history:-

Events outside of the study/experiment or between repeated measures of the dependent variable may affect participants' responses to the program. Participants may start to monitor their diet and this may lead to observed differences in the study.

maturation:-

Maturation refers to changes in the participants during the course of the experiment or even between measurements. For example, young children might mature and their weight may fluctuate.
