An experiment to study the effect of a treatment on 50 organisms was conducted. Data on 8 parameters (variables), to study the effect of the treatment, was recorded (one set under control and other under treatment effect). The data was recorded at two time intervals (30 days after treatment and 60 days after treatment).
Can u suggest a statistical method to analyze the above data so as to effectively bring about the treatment effect, the effect of the individual organism and time interval effect? And the interaction effect among all the three. Does the method vary if we study only the treatment and organism effect and their interactions?
I would be grateful if someone would suggest suitable method to analyze the data with a brief description.
