Which of the following is NOT a way to reduce random error? Increase sample size Change study design Randomization Improve instrumentation Ensure representativeness True/False: Random errors are more serious for the validity of a study than systematic errors. A group of women with a family history of breast cancer enroll themselves into a study that aims to reduce incidence of breast cancer. This is an example of what type of bias? Surveillance bias Nonresponse bias Recall bias Prevarication bias Misclassification...

A carbon tax is likely to be regressive (it will hurt the poor more than the rich because it takes a bigger percentage of their income). Regardless of your opinion on question 1, if a carbon tax was adopted what should we do with the money? We have several choices: (a) use it to fund more green research, (b) put it in the general fund (to be spent on anything), (c) lower payroll taxes on the bottom 40% (by the...

Identify the consequence (i.e. increase, decrease, or none) that the following procedures are likely to to have on both bias and sampling error in an experimental study. 1) Increasing sample size? Bias: Sampling error: 2) Assigning treatment to subjects alphabetically, not randomly? Bias: Sampling error: 3) Applying every treatment to every experimental unit in random order? Bias: Sampling error: 4) Testing only one treatment group, without a control group? Bias: Sampling error:
(05.01 LC) A polling company has decided to increase the size of its random sample of voters from about 2,000 people to about 4,500 people right before an election. A poll was designed to estimate the proportion of voters who favor a new law to set an 11 p.m. curfew for teenagers. What is the effect of this increase? (4 points) a To reduce the bias of the estimate b To increase the bias of the estimate c To reduce...
Identify the consequences (i.e., increase, decrease, or none) that the following procedures are likely to have on BOTH bias and sampling error in an observational study. Select both that apply. a. Planning for data loss. Bias: sampling error: b. Taking measurements of the subjects while unaware of which subjects belong to which group. Bias: sampling error: c. Including only one sex and age group in the study. Bias: sampling error: d. Adjusting for body size using analysis of covariance. Bias:...
