Question

Statistics provide an essential tool for analyzing your experimental results. Most importantly, statistical formulas allow the investigator to mathematically calculate the chance that what appears to be an experimental correlation is simply a coincidence. 1. Which column in Table 3 contains the independent variable? _____ 4. Which column contains the dependent variable? _____ 5. Which columns contain standardized variables? _____ 6. Which rows in Table 2 have the control setup? How do you know_____

Explanation / Answer

4. Dependent variable is a part of experiment that is effected by change in the independent variable . here the column six that is red blood cell count is a dependent variable that change according to change in independent variable.

5. Standerized variable also called control variable remain constant throughout the experiment. By keeping this variable constant you will observe how independent variable is having an effect. Here column 3 is standerized variable that is total food ration(g food/kg of body mass).

1. Independent variable is aspect of experiment means a variable that is changed or manipulated by investigator to find the answer of experiment. Here, the dose of pesticide is manipulated or change to find out the effect on red blood cell count. So, column 4 is a independent variable means dose of pestiside (ml/kg of body mass).
