Question
You are given the following data on the ages of students in my micro class: { 17, 45, 33, 32, 38, 28, 27, 22, 26, 29, 40, 19, 18, 34, 33, 28, 27, 18, 19, 23) a. Construct a frequency and relative frequency distribution using the table below. b. Construct a frequency Histogram of the data. c. Comment on the shape of the distribution? Does the shape tell you anything? Explain. The Histogram above as skewed right. Which means that there are fewer individuals in the Micro class above the age of 35 than below the age 35.Explanation / Answer
A distribution skewed to the right is said to be positively skewed. This kind of distribution has a large number of occurrences in the lower value cells (left side) and few in the upper value cells (right side). A skewed distribution can result when data is gathered from a system with has a boundary such as zero. In other words, all the collected data has values greater than zero.
If the histogram is skewed right, the mean is greater than the median.
This is the case because skewed-right data have a few large values that drive the mean upward but do not affect where the exact middle of the data is (that is, the median).
