PROGRAM EXPLANATION

Algorithm and explanation

Import the required standard-library tools and prepare the sample data for calculate standard deviation.
Process the data step by step using Standard deviation.
Display the result for calculate standard deviation and compare it with the documented sample output.

This example of calculate standard deviation processes the sample values in a controlled iteration. It demonstrates Standard deviation and prints a deterministic result that can be checked against the sample output.

DEBUGGING CHECKLIST

Common mistakes

Check this

For calculate standard deviation, keep the data shape and value types consistent with Standard deviation.

Check this

Keep every dependent statement inside the correct indented Python block.

Check this

Check denominators, numeric ranges and rounding before comparing the calculated value.

Try it yourself

Practice: Run the program with the sample input, predict its output, and then test one boundary case of your own.
