Implementing Moving Average | Dataford Interview Questions

Write a function to calculate the moving average of a given dataset.

Implement calculate_moving_average(data, window_size). Return a list containing the average of every contiguous window of window_size elements. Return an empty list when the window is larger than the dataset. The output may contain floating-point values.

Input and Output

data: a list of numbers.
window_size: a positive integer.
Return: a list of numeric averages, ordered from the first window to the last.

Constraints

0 <= len(data) <= 10^5
1 <= window_size
data contains integers or floating-point numbers
The output contains max(0, len(data) - window_size + 1) values

Function Signature

def calculate_moving_average(data, window_size):
