## What is considered a high variance?

Variance measures how far a set of data is spread out. A variance of zero indicates that all of the data values are identical. A high variance indicates that the data points are very spread out from the mean, and from one another. Variance is the average of the squared distances from each point to the mean.

## How do you interpret a range?

Interpretation. Use the range to understand the amount of dispersion in the data. A large range value indicates greater dispersion in the data. A small range value indicates that there is less dispersion in the data.

**How do you do range?**

Summary: The range of a set of data is the difference between the highest and lowest values in the set. To find the range, first order the data from least to greatest. Then subtract the smallest value from the largest value in the set.

**How do you write the range of a function?**

Overall, the steps for algebraically finding the range of a function are:Write down y=f(x) and then solve the equation for x, giving something of the form x=g(y).Find the domain of g(y), and this will be the range of f(x).If you can’t seem to solve for x, then try graphing the function to find the range.

### How do I calculate the 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.

### How do you find 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.

**Can there be two 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).
