The standard deviation is a measure of how far away from the mean each observation deviates from the mean.
What is the standard deviation?
- The standard deviation is a statistic that expresses how much variance or dispersion there is in a group of numbers.
- While a high standard deviation suggests that the values are dispersed over a wider range, a low standard deviation suggests that the values tend to be close to the mean (also known as the anticipated value) of the collection.
- Standard deviation is most usually denoted in mathematical literature and equations by the lowercase Greek letter (sigma), which stands for the population standard deviation, or by the Latin sign s, which stands for the sample standard deviation. The abbreviation for
- standard deviation
- is SD.
- The mean and standard deviation of a normal distribution are both zero.
The mean would be 5 x 0 + 8 = 8.
The standard deviation would be 5 x 1 = 5.

Answer:
Charts are the graphic representation of data.
Explanation:
There are several types of chart and data can be represented in different ways, such as bars (the chart is called <em>bars chart,</em>) lines (<em>line chart</em>) or slices (as in a <em>pie chart</em>.) They are used to make people understand data in an easier way because they are friendlier than raw information, even though there are large amounts of data contained in them.
Another important fact is the title of the chart, since it summarizes its main intention. If the chart contains multiple variables, it is necessary to indicate them with a legend or key. The chart also contains axes, usually <em>x</em> and <em>y</em>. using these elements, much information can be inferred, such as the trends and how they change through time.
