Question

What is the mean and median , mode number of infected corn stalks in a given row?

Corn crop is often prone to contracting a disease called leaf blight from a type of fungus. This fungal
group is thought to be associated with a type of pesticide used on the crop. A scientist runs an
experiment in a lab where he sets up 100 rows of 6 corn stalks and treats them with a fixed
concentration of a pesticide to see if he can determine that the pesticide does in fact cause the leaf
blight. The table below depicts the results of the experiment:

Definition Definition Measure of central tendency that is the value that occurs most frequently in a data set. A data set may have more than one mode if multiple categories repeat an equal number of times. For example, in a data set with five item—3, 5, 5, 29, 473—the mode is 5 because it occurs twice and no other value occurs more than once. On a histogram or bar chart, the element with the highest bar represents the mode. Therefore, the mode is sometimes considered the most popular option. The mode is useful for nominal or categorical data (e.g., the most common color car that users purchase), but it is problematic for continuous data because it is more likely not to have any value that is more frequent than the other.
