**2 . CSV file upload method**

For ungrouped data

Our main objective is just to calculate the mean , standard deviation and variance for the whole data in same time. The maximum file size for CSV which is supportive is of 2 MB not more than that. So , this calculator of standard deviation has only one column for inputting data that’s why the file size of CSV must not increase more than 2 MB. If there will be any row in the CSV file with empty data then it will be ignored automatically.

1 . You have to validate your CSV file ( .csv file extension ) data and make sure that you file does not contain any non real number. You can put up the column name or data name in the first row or you can also choose the option of skip first row of you do not want it.

2 . Now , the first column data is the main element of the CSV file , it must be the data set or the real number only. You are allowed to take only one column data value for calculating the value of sample deviation of the data. Now , you Abe to customize your CSV file to make the first column as the primary data which is fir calculation to avoid the assumption of the calculator that your first column data is your input data.

3 . Now , you have to select the option of ungrouped data for calculating the value of standard deviation for your all data at same time.

4 . Next you have to select on the option of Yes if you wanted your first row to be ignored otherwise you have to select the option of No .

5 . After it you have to choose your preferred CSV file which contains the data set.

6 . Now , click on the upload button for calculating the Standard Deviation.

For grouped data

You can group up your data on the basis of its nature and can calculate the mean, standard deviation and variance value for the each group of your data set separately. If you upload any grouped or ungrounded CSV file ten it will get sorted and grouped by this calculator on it’s own. So , it is not necessary to group your data separately for calculating the standard deviation for any group data. As we told you earlier the file size of CSV should not exceed than 2 MB. For the grouped data this calculator requires the two columns which can be the group data column for input.

1 . First of all you have to verify your CSV data file and make sure that all of the numbers in file are real numbers except in the first row. You can out up the column name or data name in the first row or you can also choose the option of skip first row of you do not want it.

2 . In the CSV file the first column data should be the set of data and real numbers only and the second column of data should also be of same category.

3 . Now , you have to select the option of grouped data for calculating the value of standard deviation for all of your data at same time.

4 . Now , you have to select the YES option if wanted to ignore the first row otherwise simply select the option of NO.

5 . Next , you have to choose the CSV file which contains data.

6 . Now, click on the upload button for calculating the standard deviation.

7 . You will get your calculated result on your screen note it down. Make it remember that this calculator will not save your data in any means or situation.

**3 . Text file upload method for calculating the standard deviation**

For ungrouped data
