A researcher is interested in understanding if perfume affects how attractive a person is perceived to
be. To examine this phenomenon, the research randomly assigns the participants to rate the
attractiveness of an individual from one of three groups: no perfume, a small amount of perfume, and a
large amount of perfume. Below are the ratings to how attractive the participants find the individual:
NO Perfume A SMALL Amount of Perfume A LARGE Amount of Perfume
4 6 0
5 3 1
3 5 0
5 4 1
4 5 2
3 4 2
5 3 1
3 6 1

This means that changing levels of the IV explained what percent of the DV ? For the perfume study, the studentized range statistic value was? The HSD value was?

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 + ...
