Why are the mean and median not good descriptors for a bimodal data set?
5. Consider the following data. 1,9,10,3,12,7 What is the mean? What is the median ? Determine if the data set is unimodal, bimodal, multimodal, or has no mode. Identify the mode(s), if any exist. Separate multiple modes with commas, if necessary. Selecting an option will display any text boxes needed to complete your answer. A. No Mode B.Unimodal C. Bimodal D. Multimodal
Find the mean, median, and mode for the given set of ungrouped data. 2,3,3,3,3,4,5,5,5,5 mean = median = Identify the mode(s) O 2,3 0 1,3 1,2 O 3,5
If the median of a set of data is equal to the mean, then(a) The data are Normally distributed.(b) The data are approximately Normally distributed.(c) The distribution is skewed.(d) The distribution is symmetric.(e) One can’t say anything about the shape of the distribution with any certainty.
Suppose you have a data set and the mean, median and the standard deviation are 10, 10 and 2, respectively. Someone multiplies all your data points by 3. Call these data the new data. The mean of the new data will be _______________________ The Median of the new data will be _______________________ The standard deviation of the new will be _______________________ The variance of the new will be _______________________––
How is the mean different from the median of a data set? How is the range different from the standard deviation of a data set? Additionally, using the data set {56, 67, 77, 92, 100, 12} determine the value for each of these terms.
A data set has a mean of 6.5 and a median of 4. What shape would you expect this data set to take on? Select one: a. Skewed left b. Skewed right O c. Symmetric
Calculating Mean, Median, and Mode (Individual Data) Individual data – represents individual values in a set. Mean – is the average value of the values in a set. It is calculated by dividing the sum of the individual values in a set by the number of values in that set. Median – better represents a measure of central than the mean in a set of data that are skewed one direction or another. To calculate the median value of individual...

Explain why a truncated histogram indicates that the data has been fudged and why a bimodal histogram indicates that two populations are represented in the data. Describe how two populations might be present in data from a call center.
