Passage

A researcher wanted to study the effect of a specific drug on the activity of rats. He suspected if the effect of the drug is moderated by temperature. He varied drug dosage (A) at three levels-no drug (placebo), low drug dosage (5 mg/kg body-weight) and high drug dosage (10 mg/kg bodyweight). He varied temperature (B) at two levels - 25 degree Celsius and 39 degree Celsius. Fifteen rats were randomly assigned to each of the six groups. The activity scores for each rate were obtained through activity wheel. The cell means and standard deviations for activity scores were obtained for the six cells. All the cells had comparable standard deviations. A suitable analysis of variance was carried out using the activity scores as the dependent variable. One of the interesting finding in this research was that the F ratio defined as “MSA B/MSE” was statistically significant at. 01 level.
