Example on How to Find the Standard Deviation and Variance

Our Sample Standard Deviation Calculator Generates accurate results for standard deviation and variance in microseconds. All you have to do is enter the values accurately.

Consider the example for a set of values in X = 5,10,15,20,25

To find the standard deviation and variance in the Standard deviation calculator, you must determine the mean.

Mean = Sum of values in the set (X)/ Number of values (N)

= (5+10+15+20+25)/5

=75/5

=15.

Now, 

Σⁿ_i=1(x_i- µ)²/n-1 is the formula to find the variance.

However, our experts share a simple trick to calculate the variance quickly.

 You must first subtract the mean from each value of the set X

5-15= -10

10-15= -5

15-15=0

20-15=5

25-15=10

Then, you square all the answers.

(-10)² =100

(-5)²=25

(0)²=0

(5)²=25

(10)² =100

Add all the squared numbers

100 + 25 + 0 + 25 + 100 = 250

Divide the sum of squares by (n-1)

250 / (5-1) = 250 / 4 = 62.5

Therefore, the variance is 62.5

The formulae for standard deviation is

 

However, our experts suggest another simple method of calculating the Standard Deviation.

You just have to calculate the square root of variance = √62.5=7.905

Population Variance Formula and Sample Variance Formula

You use the Standard Deviation Calculator with Work numerous times to calculate the variance. However, have you ever wondered what the variance is? Well, variance is the measurement of the spread within a set of data. It is of 2 types:

1. Population variance – measures the spread of the data in a specific population denoted by the symbol σ² where,
   

Here, N = population size filled with x_1…x_N variables, µ = mean of the population.

2. Sample variance – measures the degree to which the data is spread out denoted by the symbol s² where,

s²=1/n−1n∑i=1(xi−¯x)².

Here, n is the size of the data.

Consider the example to understand the difference between the sample variance and population variance. If you want to know the length of every word on this page, you need a population variance. However, you can calculate the sample variance with just the length of any 10 random words.

Population Standard Deviation Formula and Sample Standard Deviation Formula

When you calculate standard deviation, you calculate the spread of data distribution. Simply put, the distance between data and its mean. However, what type of Standard Deviation Calculator you use depends on whether you need to calculate the entire population of a region or the sample of its own.

Thus, you may use 2 types of standard deviation calculators.

1. Population standard deviation calculator – uses the formulae

σ=N∑(xi​−μ)2​

2. Sample standard deviation calculator – uses the formulae

sx​=n−1∑(xi​−xˉ)2​​

Applications of Standard Deviation

Do you know why Online Standard Deviation Calculators are so popular? it is because people use Standard deviation calculators for a number of purposes:

• Grade your exam score

A Population Standard deviation calculator helps determine your performance throughout the year. All your teacher needs to do is find the mean, then the variance, and the square root of the variance value. Finally, he must tally the results with scores noted before. It will help him assess your yearly performance.

• Determine market survey results

A market researcher can examine the recent market survey report ranking each product chronologically. He then uses a sample standard deviation calculator to measure the sample standard deviation of the survey ranking and predict if the customers will like the product in the future.

Analyze the reliability of weather forecast

Suppose a reporter gets a weekly weather report of 2 cities, A and B.  he may compare the temperature of the two cities by calculating the mean, variance, and Standard Deviation of the individual cities using a Standard Deviation Calculator with Steps. The city with the least deviation will depict the more reliable result.

Most Popular Questions Searched By Students:

 Q. What is the Standard Deviation?

Ans. Standard deviation measures the dispersion of values in a set of data. The lower the value of the standard deviation, the closer are the data points located to the mean. In contrast, a high standard deviation indicates a wider range of values.

Q. What Does a Large Standard Deviation Imply?

Ans. A large or higher value in the standard deviation implies that the data values are more scattered from the mean. It implies a wider distance from the mean value.

 Q. What is the Variance?

Ans. Variance is the value to determine the spread of the data in a given region. Population variance calculates the entire spread of the data, while sample variance examines the degree to which the data is spread.

Q. How many Symbols for the Standard Deviation?

Ans. Standard deviation is measured with two symbols:

• “σ”- to indicate a random variable in standard variation
• “s”- to indicate a sample.
