Does average mean most?

We use three different types of average in maths: the mean, the mode and the median, each of which describes a different ‘normal’ value.

The mean is what you get if you share everything equally, the mode is the most common value, and the median is the value in the middle of a set of data..

How do you do an average?

The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

Why is my median 0?

Since the median is the middle number when they are sorted from smallest to largest, the middle number is zero. If zero appears twice in the list then, since the mode is larger than zero, the other three numbers must all have the same valus and be larger than zero. In this case the mean could not be zero.

What mode means?

The mode is the number that appears most frequently in a data set. A set of numbers may have one mode, more than one mode, or no mode at all. Other popular measures of central tendency include the mean, or the average (mean) of a set, and the median, the middle value in a set.

What is very true?
