Suppose,as a researcher,you hypothesize that young school children engage in less cooperative play behavior when they have access to playground equipment than when playground equipment is inaccessible to them.To examine your hypothesis,which method of observation would you be best advised to use?

A) direct
B) descriptive
C) participant
D) vicarious

Direct observation would allow the researcher to physically observe and record the behavior of young school children during playtime when they have access to playground equipment and when they do not. This method would provide accurate and objective data to test the hypothesis. Descriptive observation may provide some insight into the behavior, but would not allow for direct comparison between access and non-access to playground equipment. Participant observation would involve the researcher actively participating in the play behavior, which could potentially bias the results. Vicarious observation would involve the researcher relying on second-hand accounts or recordings of the behavior, which would not provide the level of detail needed to test the hypothesis.
