Challenge 3: Statistical Insights

Gleaning insights from your data often involves statistical analysis. NumPy shines here with its:

Rich Set of Functions: From means and medians to variances and percentiles, NumPy has it covered.
Performance: NumPy's statistical functions are optimized, making them notably fast on large datasets.
Reliability: The library's tried and tested functions ensure consistent and accurate results.

Harnessing NumPy's statistical tools can empower you to extract meaningful patterns and insights from your data, which is a pivotal step in many data science projects.

Завдання

Numpy provides functions to obtain insights about data.

Compute the mean of the data.
Get the standard deviation of the data.
Identify the value in the array that is nearest to the mean value of the array.
