This is determined by adding all the numbers in a set of data and then dividing by the . number of values. Median*: This is the middle number in a set of data. If the there is an even set of numbers in the . data, then take the average of the two middle numbers. Ex: 2, 3, 4, 8, 12, 16, 20 median = 8

must average those two middle numbers to get the median value. Average: 67 + 75 = 142 = 71 is the median value. 2 2. C. Finding the Mode. The mode of a set of values is the value that occurs most often. A set of values may have more than one mode or no mode. Example #1: Find the mode of 15, 21, 26, 25, 21, 23, 28, 21

These values were each obtained by taking the average of 25 values randomly chosen between 0 and 50 (i.e., 625 random numbers were used). Divide the range by the number of classes (let's use 5 in this case): (30.91 – 19.55) / 5 = 2.272. So the class width is 2.28 (round up to the next value, in hundredths). Here's the frequency distribution.

On the other hand, finding the average of two numbers is fairly easy and need not be done on a computer. Algorithms are sequential in nature. There are examples where several instructions in an algorithm are executed at the same time, but generally, we can think of the instructions in an algorithm as being executed one at time.

Arithmetic and Geometric Means
The answer is: Both are correct. James's reasoning is based on the average or arithmetic mean of two numbers. Enobong's reasoning is based on the geometric mean. Both means are used extensively in mathematics and in everyday life. The average or arithmetic mean of two numbers is found by calculating the sum of the two numbers and dividing by two.
