Comparing the mean and median for different types of distributions of data

Describe how the mean compares to the median for a distribution as follows: a. skewed to the left, b. skewed to the right, c. symmetric

Median, Mode, Range, Variance and Standard Deviation are determined.

9.50 5.00 8.02 6.00 3.40 8.33 8.35 10.49 5.32 4.08 9.20 5.40 6.17 3.00 2.32 8.35 8.02 6.00 5.15 9.00 Using this data (in ungrouped form) compute; Median, Mode, Range, Variance and Standard Deviation (using computational formula).

Construct a Frequency Distribution with a class interval of 10, starting with 30.

The caffeine content of 20 brands of regular coffee is shown below. 80 82 89 85 87 30 33 44 40 46 50 55 60 62 71 90 92 75 63 65. Thus, this job helps to construct a Frequency Distribution with a class interval of 10, starting with 30. It shows the class limits, class boundaries, class midpoints, class frequencies and class cumulative less than frequencies.

Help with interpreting the results is given.

Shortly after their graduation, John and Mary bought two used vehicles. To satisfy their curiousity, they started to record their kilometrage each time they filled their gas tanks. After ten weeks, their records show the following numbers of kilometres per litre. Mary: 17, 19, 16, 15, 18, 18, 20, 22, 15, 15 Mean= 17.5 Standard Deviation= 2.37 John: 9, 7, 16, 20, 23, 25, 29, 13, 15, 18 Mean= 17.5 Standard Deviation= 6.96 Interpret these results.

Mean, Median, and Mode are computed.

The following data show the age distribution of the top 14 doctors in the emergency faculty of a local hospital. Age Frequency 35-39 2 40-44 2 45-49 1 50-54 3 55-59 4 60-64 2 Compute the Mean, Median and Mode.
