Which of the following statements is (are) TRUE?
1A two-way table is a useful way to summarize data when two categorical variables are measured on the same individuals or cases.
2Simpson’s paradox is an example of the potential effect of a lurking variable on an observed association between two categorical variables.
3If the counts in each cell of a two-way table are divided by the total number of observations, the result is the joint distribution of the two categorical variables.
4All of the above are true.
Homework Answers
A two-way table is a useful way to summarize data when two categorical variables are measured on the same individuals or cases---True.
Simpson’s paradox is an example of the potential effect of a lurking variable on an observed association between two categorical variables---True.
If the counts in each cell of a two-way table are divided by the total number of observations, the result is the joint distribution of the two categorical variables--True.
So the Option is: 4 All of the above are true.

Which of the following is a true statement about Simpson’s Paradox?
Which of the following is a true statement about Simpson’s Paradox? At least one answer is correct, but more than one answer may be correct; for full credit, select all that are correct. Simpson’s Paradox can arise when tables of data on the same categorical variables for different groups are aggregated. Simpson’s Paradox can arise due to lurking categorical variables. The paradox is that an association between two categorical variables that holds for all of of several groups can reverse...

(1 point) Recall in the course we learnt how to display data of two categorical variables by means of a contingency table. In this question, we will formulate a measure to quantify the level of association between the two categorical variables. Such a measure is often used in a statistical test called Chi-square test for assessing whether there is an association between two categorical variables. This question is also used to motivate the learning of independence and to connect the...

Researchers Vogel et al.

Of the 9739 women randomly assigned to use tamoxifen daily, 158 developed invasive breast cancer sometime during the next five years, compared to 151 in the group of 10162 who were randomly assigned to use raloxifene daily.

The following statements apply to concepts and material discussed in Chapter 15; identify which statement is TRUE. Answers: A common ancestor of two species on evolutionary trees can be found at the point where the two branches meet. Humans evolved from Neanderthals about 50,000 years ago. Mitochondrial DNA is not particularly useful when trying to determine the movement pattern of humans historically across the globe. Scientists can estimate when species diverged from a common ancestor by comparing their Karyotypes. We...
