Question
The Centers for Medicare and Medicaid Services (CMS) use their databases containing medical claims data to summarize different health measures. Using data collected for the population of Medicare beneficiaries, the CMS create tables that summarize chronic disease prevalences. Disease prevalance is the percentage in a population that have a certain disease at a point in time.
A portion of a table summarizing chronic disease prevalences by state for 2015 is given. This table portion includes prevalence data for a subset of the chronic diseases at the state level for several states.
Identify each piece of data as a case, variable, label, or value.
The prevalence of atrial fibrilation in each state
The name of each state
In 2015, the prevalence of asthma in Florida was 9.1%.
The state of Idaho
As of 2015, 17.9% of the Medicare beneficiary population in Colorado had diabetes.

Explanation / Answer
Cases refers the objects in the collection. Each case has one or more attributes or qualities, called variables. Usually, there are many possible variables. The researcher chooses those that are of interest, often drawing on detailed knowledge of the system that is under study. The researcher measures or observes the value of each variable for each case. The result is a table, also known as a data frame.
A label is used to identify the case in a table or dataframe.
Thus,
(a) The prevalence of atrial fibrilation in each state is a "variable" since it refers to a distinct feature value for each state.
(b) The name of each state is a "label" since it acts as an identification for each case.
(c) In 2015, the prevalence of asthma in Florida was 9.1%. Since this depicts a single variable information for a particular case, it is a "value".
(d) The state of Idaho represents a "case" whose each feature represents a number of particular disease prevalences.
(e) As of 2015, 17.9% of the Medicare beneficiary population in Colorado had diabetes.
This depicts a "value" as it represents a particular entry for a variable of a case.
(f) The prevalence of asthma in each state
The number of asthma in the data frame represents a "variable".
