Description
A researcher has investigated the relationship between IQ and Grade point average, the correlation is .75. What is the connection to correlation and causation?
User generated content is uploaded by users for the purposes of learning and should be used following Studypool's honor code & terms of service.
Explanation & Answer
The correlation is very high, meaning a close connection between these two variables (as you would expect - an intelligent study is likely to get a high score).
Correlation does not give the cause, which has to be investigated separately. We cannot say a high IQ causes the student to get high marks; many other factors are also involved even if IQ is one such factor.

STAT2002 Walden University Testing Manufacturer’s MPG Claim Analysis
This Assignment consists of two parts. You will complete and submit Part 1 this week, and you will complete and submit Part 2 in Week 5.Companies often develop and test hypotheses about their products. For example, car manufacturers will test their cars to determine fuel efficiency and miles per gallon. To ensure that products are safe and that they perform as advertised, regulatory and consumer protection groups also test companies’ claims.For this Assignment, you are working at a firm that conducts independent testing for heavy industry. Recently, an automobile manufacturer has been in the news for complaints about the highway gas mileage of their latest model minivan. You receive a contract from a consumer action group to test and write a report on the company’s claim that its minivans get 28 miles per gallon on the highway. The car company agrees to allow you to select randomly 35 low-mileage fleet minivans to test their highway mileage. Your test results gave you the following data: 29.7 24.5 27.1 29.8 29.2 27.0 27.8 24.1 29.3 25.9 26.2 24.5 32.8 26.8 27.8 24.0 23.6 29.2 26.5 27.7 27.1 23.7 24.1 27.2 25.9 26.7 27.8 27.3 27.6 22.8 25.3 26.6 26.4 27.1 26.1To prepare for this Assignment:Review this week’s Learning Resources.Refer to the scenario above and the data that was provided by the car company.Refer to the Academic Writing Expectations for 2000/3000-Level Courses as you compose your Assignment.By Day 7Submit Part 1 of your report according to the following prompts.Part 1: Sample Mean, Standard Deviation, and Confidence IntervalComplete the following and include your results and responses in your report:Include a brief introduction that provides a context for the assignment you have been given by your firm.Calculate a 95% confidence interval around your sample mean. (75 words, or 1 paragraph)Note: Include your calculations. If your calculations are submitted separately, make note of where they can be found.Is the company’s claimed mean inside your confidence interval? (75 words, or 1 paragraph)What does that result indicate about the company’s claim? (75 words, or 1 paragraph)Note: For each prompt, be sure to reference at least one scholarly source to support your answer.

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

PSYCH 655 University of Phoenix Week 3 Psychological Test Construction Discussion Question
Hello, In week’s one and two, we looked at the history of psychological assessment and factors that contribute to a testing being a good test (i.e., reliability, validity, ethics, etc.). In week 3, we explore what makes a test useful and use that to determine methods for test construction. Respond to the following questions in a substantive way integrating information from your text or other scholarly sources (please include citations and references for your work):1. How would you go about making a judgment regarding the utility of a published test? What factors would you consider? What resources would you use? 2. What factors concerning test utility would you consider as you work through the process of test construction?3. What are factors that need to be considered early in test construction to insure that the process proceeds accurately and you end up with a useful test?4. Consider that you are constructing a test on test anxiety, what are some examples of items you would include in an assessment of an individual's level of test anxiety? How would you determine which items should be included in the assessment? How would you evaluate the appropriateness of your items and each item's performance in the assessment?
