Ashford University Sampling Methods Relating to Statistics Discussion Post
THIS IS A DISCUSSION POST ONLY!150 to 250 WordsThis video discusses sampling in the context of how estimates of population parameters are obtained. It refers to Video 1: What is an Average? where we obtained an “average of 1.89 feet per person.” It points out that applying this statistic depends on thinking through whom the population is meant to be, and that depends on the study question (i.e., “If you want to understand your answer, you really have to work out carefully what your question is.”).As the sample statistic was derived from a bunch of kids heading to the playground, plus a one-legged man who we asked to show up, we conclude that the sample was a bad one. We explain that random sampling is generally a good way of obtaining a representative sample such that you can be confident that the sample statistic is a good estimate of the population parameter.Respond to the following response below:Magazines often report surveys giving statistics such as “63% of women expect the man to pay on the first date.” Are these random samples? These surveys are most definitely not random – they are typically click-through from the magazine website – and so can provide an opportunity to discuss the sort of biases that can result from lack of random sampling.Video 3 Below:https://mediaplayer.pearsoncmg.com/assets/MsQQxcXFvHB_VZh1oA5V861T4AL2Cenj

Need statistics help with Churn of the cellphone market
Hello,I am having trouble with the following problem. The problem file is attached.
. The file C03_03.xlsx contains data on over 2000 customers
of a particular cellular phone company. Each row contains the activity of a
particular customer for a given time period, and the last column indicates
whether the customer churned during this time period. Use the tools in this
chapter (and possibly the previous chapter) to learn (1) how these variables
are distributed, (2) how the variables in columns B–R are related to each
other, and (3) how the variables in columns B–R are related to the Churn
variable in column S. Write a short report of your findings, including any
recommendations you would make to the company to reduce churn.
