Why wouldn't the answer for problem 4 be the members of each household?

The members of each household receive the same diet, but each household could have a different diet. Since the diet is consistent in the household, the household is the experimental unit.

why didnt seattle just run the ball..

It was the right call but Malcolm Butler just made a great play.

Words are slippery. The last question expects as correct answer the households, not their members. Makes me scratch my head and and ironically conclude: "Aha! So it is the households who eat (or not) the kale, not the household members".

That is a funny point, but the household is the whole of the household members. We were comparing different households as a whole and not *a* households individual members. Hope this helps, - Convenient Colleague

If the household members are not the experimental units, then what are they?

If the household members are not considered the experimental units, then they are the subjects or participants of the experiment. In this study, the household members are the individuals whose blood pressure measurements are being recorded before and after the two-month period. Therefore, they are the subjects or participants of the study.

What can be the possible source of bias here ?

Possible sources of bias in the study could include: Selection bias: if households are not randomly selected or assigned to treatment groups. Measurement bias: if blood pressure measurements are inaccurate or inconsistent. Non-response bias: if participants drop out or refuse to participate. Reporting bias: if participants do not accurately report their adherence to the diet plan. Observer bias: if individuals recording blood pressure are aware of the assigned treatment group and this influences their measurements.

  Yes, in Problem 4, it could be argued that the experimental units should encompass all the people in the house rather than just referring to the household. This distinction is crucial because the treatment (kale-based or kale-free diet) is applied at the household level, but the responses (changes in blood pressure) may vary among individual members within each household. Therefore, specifying the experimental units as "the members of each household" would provide a more comprehensive understanding of who or what is being studied in relation to the treatments and responses.

  In Problem 4, the experimental units are correctly identified as "The households." However, it's essential to note that while the households are the experimental units in this study design, the analysis of the data collected (such as changes in blood pressure) may involve individual members within each household. So, each individual member could be considered a unit of analysis within the households.

  Confounding refers to a situation in which the effect of one variable on the outcome of interest (the dependent variable) is mixed with the effect of another variable that is not accounted for in the analysis. Essentially, a confounding variable is a third variable that is related to both the independent variable (the variable being studied or manipulated) and the dependent variable (the outcome of interest).
