describe what an anova test or experiment is? describe its main components andhow it differs from observational study?
Homework Answers
Observational studies are studies where researchers observe the affect of a risk factor, treatment without trying to change who is or is not exposed to it. We measure or survey members of the sample without trying to affect them
Experimental studies are the studies where researchers introduce an intervention and study the effects. Experimental studies are randomized, meaning the sample subjects are grouped by chance.
ANOVA is a statistical technique which checks if the means of two or more groups are significantly different from each other. By comparing the means of different samples it checks the effect of one or more factors.

Part I. Understanding What Makes an Experiment 1) Please identify the 3 vital components of an experiment. After identifying each component, write at least one sentence elaborating on/explaining each component (10 points) Answer – The most conventional type of experiment involves three major pairs of components: independent and dependent variables, pretesting and post testing, and experimental and control groups. An experiment examines the effects of independent variable on a dependent variable. 1- Manipulate at least one independent variable. This means...
