Welcome to your interview.
The question is on your right: Mean and Standard Deviation Basics. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
You are given a small numeric dataset and asked to summarize its center and spread. This is a basic descriptive statistics task that often comes up before deeper analysis.
Write a function to calculate the mean and standard deviation of a dataset.
