The sampling mean most likely follows a normal distribution. In this case, the standard error of the mean (SEM) can be calculated using the following equation:

σ _{x̄} =

Based on the SEM, the following are the margins of error (or confidence intervals) at different confidence levels. Depending on the field of study, a confidence level of 95% (or statistical significance of 5%) is typically used for data representation.

Standard Deviation Calculator For a given data set standard deviation is defined as the measurement of the spread of data or sometimes it is describe as the distribution of the data of a data set.

It is used for defining the diversity of data in probability and statistics. It is calculated on the basis of average mean or mode that how much the value of a given data set is dispersed.

If the calculated standard deviation is less that means the dispersion of the data is low means it is very close to the mean or mode value and if the value of standard deviation is more, that means the value of the data set is much more dispersed.

In the statistics calculation of standard deviation is very much important and also very much in demand.

Standard Deviation is the part of statistics that is defined in the data set of value that is the diversity of the value.

- The standard deviation formula may look confusing, but it will make sense after we break it down.
- Step 1: Find the mean.
- Step 2: For each data point, find the square of its distance to the mean.
- Step 2: For each data point, find the square of its distance to the mean.
- Step 3: Sum the values from Step 2.
- Step 4: Divide by the number of data points.
- Step 5: Take the square root.

S=vS(x-x¯)2/N

where S = the standard deviation of a sample,

E means "sum of" X = each value in the data set,

X = mean of all values in the data set,

N = number of values in the data set.

Sx= is the sample standard deviation

x̅= is the sample

n= it is the number of members of a sample

xi, i = 1, ... ,n are the members of a sample
