Im not really sure where to start

Implement 4 functions: compute_mean(collection, n) Returns the mean of all items collection rounded to n decimal points (hint- look up "rounding in Python") compute_median(collection) Returns the median of all items in collection When there are an even number of items, return the lower of the two middle numbers. This is how we will define the median in algorithms throughout this course. compute_mode(collection) Returns the mode of all items in collection When there are multiple potential modes, return the lowest compute_stats (collection) Returns a three-tuple of the mean, median, and mode of a collection Starting code: def compute_mean(): pass def compute_median(): pass def compute_mode(): pass def compute_stats(): pass
