1. Radish seedlings were randomly distributed and then grown under four conditions: natural lighting, darkness, regular (incandescent) light bulb, and full spectrum light bulb (providing ultraviolet lighting). Heights of the seedlings were measured after 9 days. Mean and standard deviations for radish heights for each of the four groups with sample sizes 20, 25, 20 and 24 were calculated for an ANOVA. The Between Sum of Squares and Within Sum of Squares were found to be 665.66 and 695.97. What would be an appropriate null hypothesis?

A. The mean radish seedlings in the four given conditions are equal.

B. The four given mean radish seedlings are equal.

C. The mean seedling heights in the four given conditions are equal.

D. The four given mean conditions are equal.

2. What would be the computed F statistic?

A. 26.733

B. 0.944

C. 0.033

D. None of these

3. What is the degree of freedom of the corresponding F distribution?

A. (3, 85)

B. (4, 85)

C. (3, 89)

D. (4, 89)

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
