Hold down the spray button until the WD-40 begins to overflow from the lock opening.
Find the median of a data set with an even number of data points. Arrange the data points in ascending order of value. The median will be the sum of the two middle data points divided by 2. For example, the median of the data set {1, 2, 2, 3, 4, 5} is (2 + 3)/2 = 2.5. Calculate the mode of a data set. The mode is defined as the value in the data set that occurs most often. If more than one value occurs an equal number of times, all of these values are modes for the data set. For example, 2 and 3 are both modes for the data set (1, 2, 2, 3, 3, 4).
The median is the middle value in the list of numbers. To find the median, your numbers have to be listed in numerical order from smallest to largest, so you may have to rewrite your list before you can find the median. The mode is the value that occurs most often.
