What does mode mean median mean?

Answer 1

Mode: "most"- The number that occurs the most. There isn't always a mode. Example: 1, 2, 2, 6,2,5,6, 7,6,4,9,5,8,2 The number 2 is the mode because it occurs most frequently. The mode need not be a number, you can have a mode with qualitative data. RED RED BLUE GREEN. The mode is RED.

Mean: This is the arithmetic average. If there are n numbers, you add them up and divide by n, this is the mean. For example if n=3, there are 3 numbers. Let's say they are 1, 2, and 3. Add them up and you have 6, divide by 3 and the mean is 2.

Median: If the numbers are placed in ascending order, this is the number in the middle if you have an odd number of numbers (entries). If you have an even number of numbers, the median is the mean of the two middle numbers.

For example, 1 2, 3, the median is 2. Now look at 1, 2, 3, 4. The median is the average of 2 and 3 which is 2.5 even though this is not one of the numbers in the set.

There is some controversy over this and some people do it differently, but this method is most commonly used. It is also the one used by the TI 83 calculator.
