Assignment 3 - Practicing with functions

Learning Outcomes

• Understand what functions are and why they are used.
• Develop a function to solve a given problem.
• Write a for loop.

Problem - creating a myMean function

Write a function named myMean that uses a for loop to calculate the mean of a vector of numbers.

Recall that the mean is:

\[ \bar{x} = \frac{\sum_{i=1}^n{x_i}}{n} \]

Notes

• You should use the for loop to add up a vector of numbers. DO NOT USE THE SUM FUNCTION IN YOUR CODE!
• Create a vector of numbers to test your function on, and compare the results of your function with that of the mean function in base R.
