Notice that one month for each employee is blank.   Employee Jan Feb Mar Apr May June Saul 74 80 73 81   78 Josie 69 77 72   81 84 Please choose numbers for Saul and Josie’s sales (between 65 – 85) to complete your table.  Copy and paste the completed table into your post (control + v and then click keep formatting). Compute the mean number of sales for both workers.  Show all work and round to one decimal place. Find the range for the number of sales for both Saul and Josie.  Show all work. Explain which employee was more consistent. Justify your answer using your calculations above. To whom will you give the promotion? Explain your reasoning.

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 + ...
