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).
Best Answer: mean, median, and mode are all ways to figure what the average of a set of numbers are. mode is the number that occurs the most. mean is where you take all the numbers, add them together, an divide by the number of numbers, and median is when you organize the numbers numerically and then find the number that is in the exact middle.
