Question

a) Determine the mean of sunflower heights in the test plot which was not fertilized and fertilized.

b) Determine the median of sunflower heights in the test plot which was not fertilized and fertilized.

c) Find the Stem-leaf plot of sunflower heights in the test plot which was not fertilized and fertilized.

VI. In the following example the researcher was interested in how the application of a
fertilizer affected the height of sunflower plants. The fertilizer was applied to one
test plot and the height of n= 20 sunflower plants in that test plot were measured

Definition Definition Middle value of a data set. The median divides a data set into two halves, and it also called the 50th percentile. The median is much less affected by outliers and skewed data than the mean. If the number of elements in a dataset is odd, then the middlemost element of the data arranged in ascending or descending order is the median. If the number of elements in the dataset is even, the average of the two central elements of the arranged data is the median of the set. For example, if a dataset has five items—12, 13, 21, 27, 31—the median is the third item in ascending order, or 21. If a dataset has six items—12, 13, 21, 27, 31, 33—the median is the average of the third (21) and fourth (27) items. It is calculated as follows: (21 + 27) / 2 = 24.
