Write a function to calculate sample variance from a list of integers.
Create a function that outputs the sample variance given a list of integers. Round the result to 2 decimal places.
Example:
Input: test_list = [6, 7, 3, 9, 10, 15]
Output: get_variance(test_list) -> 13.89
Is there anything suspicious about the A/B test results with 20 variants? Your manager ran an A/B test with 20 different variants and found one significant result. Evaluate if there is anything suspicious about these results.
Write a function to return the median value of a list in O(1) time and space.
Given a list of sorted integers where more than 50% of the list is the same repeating integer, write a function to return the median value in O(1) computational time and space.
Example:
Input: li = [1,2,2]
Output: median(li) -> 2
What are the drawbacks of the given student test score data layouts?
You have data on student test scores in two different layouts. Identify the drawbacks of these layouts, suggest formatting changes for better analysis, and describe common problems in "messy" datasets.
