Concept explainers

Types of Bias

Statistics is the study of data collection, organization, analysis, interpretation, and presentation. Statistical bias is a characteristic of a statistical technique or its findings in which the expected value deviates from the actual root quantitative parameter being estimated. According to the actual definition of bias, it refers to the tendency of a statistic to overestimate or underestimate a parameter.

Find an article of your choice which uses proportions, and copy and paste the address of that article in this step. Identify at least one sample proportion within the article (you can list more than one if you like), and state what that sample proportion measures. For example, if you're told that the sample proportion of people in Renton who are taller than 5'11" is 80.7%, and you're also told that the sample size is 57, then you would state the proportion as 46/57 in your response for this part of the assignment. You will probably have to interpret what is being said in the article in order to be able to state specifically what the sample proportion represents. Also, you might not have x or n, you might only have the percentage or a decimal equivalent. Often, the size of the sample is stated somewhere in the article, and it's important to find that value. So, if n is given, please include it in this part of the assignment. If stated in the article, identify whether the sample is a…
Several years ago, two companies merged. One of the concerns after the merger was the increasing burden of retirement expenditures. An effort was made to encourage employees to participate in the 401(k) accounts. Nationwide, 63% of eligible workers participated in these accounts. The accompanying data table contains responses of 30 employees of the company when asked if they were currently participating in a 401(k) account. Complete parts a through d. Click the icon to view the data table. a. Determine the sample proportion of company workers who participate in 401(k) accounts. The sample proportion is. (Round to three decimal places as needed.) b. Determine the sampling error if in reality the company workers have the same proportion of participants in 401(k) accounts as does the rest of the nation. The error is (Round to three decimal places as needed.) c. Determine the probability that a sample proportion at least as large as that obtained in the sample would be obtained if the…
