#NAME?
You are conducting a study to evaluate the effects of fertilizer concentration on plant growth. To evaulate the effects of fertilizer concentration you randomly select 100 potato plant seedlings and you treat them with one of the four different fertilizer concentrations, and at the end of the growing season you measure the total plant biomass for each plant. You are now ready to analyse your data. Which of the following statistical analyses would you want to choose to compare the mean plant biomass for each of the fertilizer treatments?
a. |
A standard deviation test |
|
b. |
An ANOVA |
|
c. |
A t-test |
|
d. |
A standard regression analysis |
