Question

What if you need to calculate the variability of the list of numbers [1, 3, 5, 7, 9, 9]. using the help() function, what set of functions can you choose from within the statistics module after importing it from the python standard library?

a. pvariance, variance, pstdev, stdev
b. median, median low, median high, median grouped
c. mode, multi-mode, quantiles
d. mean, fmean, geometric mean, harmonic mean

Answer 1

The correct answer is Option A: To calculate the variability of a list of numbers in Python, you can use functions from the statistics module such as variance and stdev.

Step-by-step explanation:

When calculating the variability of a list of numbers in Python, you can use several functions from the statistics module.

After importing the statistics module from the Python standard library, you can choose from the following set of functions:

• pvariance: Calculates the population variance of a dataset.
• variance: Calculates the sample variance of a dataset.
• pstdev: Calculates the population standard deviation of a dataset.
• stdev: Calculates the sample standard deviation of a dataset.

To calculate the variability of the list of numbers [1, 3, 5, 7, 9, 9], you can use the variance function from the statistics module.

If you need to calculate the variability of a list of numbers, for example, [1, 3, 5, 7, 9, 9], after importing the statistics module from the Python standard library, you would use the help() function to explore the available statistical functions. Among the functions provided by the module, the set of functions that can be chosen to calculate variability includes pvariance, variance, pstdev, and stdev. These allow you to calculate the population variance, sample variance, population standard deviation, and sample standard deviation, respectively.
