What is the median of 77 and 84?

What is the median of 77 and 84?

80.5

Why do you add 1 when finding the median?

The number of numbers is N + 1 since every comma is at the lefthand side of a number and therefore the rightmost number “6” need to be added as 1. That is why the median is the number enumarated by (N + 1) / 2. You may use the “counting” strategy. Consider the set of numbers 4, 5, 6., 23.

What is the easiest way to find the mean?

How to Find the Mean. 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.

How do you calculate mode?

To find the mode, or modal value, it is best to put the numbers in order. Then count how many of each number. A number that appears most often is the mode.

What happens if there are 2 modes?

Examples of the Mode A set of numbers can have more than one mode (this is known as bimodal if there are two modes) if there are multiple numbers that occur with equal frequency, and more times than the others in the set.

Can there be 2 modes?

In a set of data, the mode is the most frequently observed data value. There may be no mode if no value appears more than any other. There may also be two modes (bimodal), three modes (trimodal), or four or more modes (multimodal).

Can there be 2 medians?

If there is an odd number of data in the list, there is only one number that is exactly in the middle of the data. But if there is an even number of data points, then there are two numbers in the middle. In that case, you have to add those two numbers together and then divide by two to find the median.
