Which variability measure (mean, median or mode) is most useful for comparing variability in two different situations, adjusting for the fact that the situations have very different average sizes? Justify your choice.
Homework Answers
Mean , median or mode are not the measure if variability, they are the measure of central tendency. In general mean and standard deviation are the best measure of the central tendency and variability respectively if the distribution is symmetrical. For skewed distribution median and IQR are better measure of central tendency and variability.
For the given scenerio mean and standard deviation appears to be best.

Suppose you are representing the employees at a large corporation during contract negotiations. You have a list of the salaries of all the employees at the corporation. The company has many lower level employees and only a few high paid management employees. There is a complicated system of raises that makes it so that there are many different salaries for the lower level employees. a. Which measure of center would you use to represent the employees? You are trying to...

Could anyone help add to my python code? I now need to calculate the mean and median. In this programming assignment you are to extend the program you wrote for Number Stats to determine the median and mode of the numbers read from the file. You are to create a program called numstat2.py that reads a series of integer numbers from a file and determines and displays the following: The name of the file. The sum of the numbers. The...

Unit 6 Lesson 3 Classwork (Adapted from Math Vision Project) Data Distribution A lot of information can be obtained from looking at data plots and their distributions. It is important when describing data that we use context to communicate the shape, center, and spread. Shape and spread: Modes: uniform (evenly spread- no obvious mode), unimodal (one main peak), bimodal (two main peaks), or multimodal (multiple locations where the data is relatively higher than others). Skewed distribution: when most data is...

program in python
Randomness can be used to improve the performance of deterministic algorithms which need to make many choices. Rather than repeatedly making fixed, hard-coded choices, a pseudorandom number generator can be used to make dynamic, unbiased choices. If the benefits of "good" choices outweigh the costs of "bad" choices, a random selection of good and bad choices can improve the performance of an algorithm Let us explore this with the QUICKSELECT algorithm. Discovered by the influential computer science...
