Question

This is Analysis of Variance question. Please help me using SAS.

The effect of the drug d-amphetamine sulfate on the behavior of rats is the object of an experiment. The behavior under study was the rate at which water-deprived rats pressed a lever to obtain water. The response was the lever press rate defined as the number of lever presses divided by the elapsed time of the session. The treatment factor levels were five different dosages of the drug in milligrams per kilogram of body weight, including a control dosage consisting of saline solution. An experiment, or run, consisted of injecting a rat with a drug dosage, and after one hour an experimental session began where a rat would receive water each time after a second lever was pressed. The experimental unit in these experiments was not a rat, but the state of a single rat during one experiment or run, since an individual rat could be used in many experiments by repeatedly injecting it with different doses of the drug (after an appropriate washout period) and by observing the lever pressing behavior. Because there was wide variability in the lever pressing rate between rats, an RCB design was used, and a rat represented the blocking factor. Each rat received all five doses in a random order with an appropriate washout period in between. Analyze the data. Do a residual analysis and determine if a transformation is necessary. Make an appropriate transformation and reanalyze.

Explanation / Answer

I hope you are looking to run it in sas. For running it in SAS, you can use the below formula:-

proc anova;

class dosage;

model rat = dosage;

run;

Lets call the dependent variable as rat and independent variable as dosage.
