A marketing research company tests the effectiveness of three new flavorings for a new sauce using a sample of 30 people, divided randomly into three groups of 10 people each.
3.
Group 1 tastes Flavor 1, Group 2 tastes Flavor 2, and Group 3 tastes Flavor 3.
* Your answer is not complete.

Each person is then given a questionnaire that evaluates how enjoyable the beverage was.
The scores are shown below. Determine whether there is a perceived significant difference between the three flavorings.

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 + ...
