### How Populations and Variables DifferTo understand statistical analysis and data collection methodologies, it is essential to differentiate between populations and variables. **Question:**Explain how populations and variables differ.**Answer Choices:**- **A.** A variable is a set of units of interest to a study. A population is a characteristic or property of the units being studied.- **B.** A population is a set of units of interest to a study. A variable is a subset of the units of a population.- **C.** A population is a set of units of interest to a study. A variable is an object upon which data is collected.- **D.** A population is a set of units of interest to a study. A variable is a characteristic or property of the units being studied.Understanding these differences is vital for the correct design and interpretation of any study. Here is a deeper look:#### PopulationsA population is the total set of units or elements that are of interest in a study. This could include people, objects, or events that researchers want to analyze for making inferences.#### VariablesA variable, on the other hand, is a characteristic, number, or quantity that can be measured or counted and varies among the units of the population. Variables are attributes that data correspond to in the study.### ConclusionThe correct answer in this context is **D.** A population is a set of units of interest to a study. A variable is a characteristic or property of the units being studied. This distinction clarifies that while populations refer to the broader set of subjects, variables are the specific traits or features measured within these subjects.

Contingency Table

A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.

Binomial Distribution

Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.

Question

### How Populations and Variables Differ

To understand statistical analysis and data collection methodologies, it is essential to differentiate between populations and variables.

**Question:**
Explain how populations and variables differ.

**Answer Choices:**

- **A.** A variable is a set of units of interest to a study. A population is a characteristic or property of the units being studied.
- **B.** A population is a set of units of interest to a study. A variable is a subset of the units of a population.
- **C.** A population is a set of units of interest to a study. A variable is an object upon which data is collected.
- **D.** A population is a set of units of interest to a study. A variable is a characteristic or property of the units being studied.

Understanding these differences is vital for the correct design and interpretation of any study. Here is a deeper look:

#### Populations
A population is the total set of units or elements that are of interest in a study. This could include people, objects, or events that researchers want to analyze for making inferences.

#### Variables
A variable, on the other hand, is a characteristic, number, or quantity that can be measured or counted and varies among the units of the population. Variables are attributes that data correspond to in the study.

### Conclusion
The correct answer in this context is **D.** A population is a set of units of interest to a study. A variable is a characteristic or property of the units being studied. This distinction clarifies that while populations refer to the broader set of subjects, variables are the specific traits or features measured within these subjects.
