Final answer:
The correct answer from the given options is option D. In one-way ANOVA, MSE is used with F-ratio as a measurement of the variance of individual observations.
Step-by-step explanation:
In one-way ANOVA, the MSE (Mean Square Error) is used with F-ratio as a measurement of the variance of individual observations.
The F-ratio is calculated by dividing the Mean Square Between (MSB) by the Mean Square Error (MSE). MSB represents the variance between groups or treatments, while MSE represents the variance within groups or treatments.
Therefore, the correct answer is d. MSE.
