Choose Your Own Question Come up with your own question you would like to be able to answer. What is the question? How might you collect data to answer this question? What would the cases be? What would the variable(s) be?

Short Answer

Expert verified
Question: 'Does the color of a product influence a customer's choice?'. The data can be collected through a study where customers choose a product from a selection of same products in different colors. Each customer will serve as an individual case. There are two variables: the color of the product, and the customer's choice.

Step by step solution

01

Defining the Question

Craft a question that intrigues you. For instance, one might ask, 'Does the color of a product influence a customer's choice?' This question allows next steps such as data collection and analysis to move forward.
02

Data Collection Method

Discuss potential ways to gather data. In this case, a hypothetical method could involve conducting a study where customers are presented with the same product in multiple colors and asked to choose one. Their choices would be recorded, providing raw data.
03

Identifying the Cases

Specify what the cases are in your study. In this instance, each customer evaluated would serve as individual case for this study.
04

Naming the Variables

Identify the variables related to the question. For this question, there are two variables: the color of the product and the customer's choice. These variables can be organized and compared to find any potential correlations.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Research Question Formulation
Formulating a research question is the cornerstone of any analytical task, serving as the guidepost for your investigation. It's important to devise a question that is clear, focused, and researchable. An example of a properly formulated research question is, 'Does the color of a product influence a customer's choice?'

This question is specific and measurable which makes it conducive for statistical analysis. To refine your question, consider the scope, relevance, and the potential impact of the answers obtained. Always remain open to refining your question as your understanding of the subject deepens.
Case Identification
In research, a 'case' can be an individual, group, event, or instance that is the subject of study. Identifying cases is essential as they are the basic units of analysis. In the context of our example, individual customers represent cases. Their selection provides a way to observe and measure the impact of the product's color on their choices.

To effectively identify cases, ensure they align with your research question and are accessible for observation or measurement. Consider also sample size and how representative your cases are of the wider population in order to generalize findings.
Variable Specification
Variables are the attributes that you measure, control, or manipulate in your study. Specifying your variables allows you to establish clear definitions and find the right methods to measure them. The example provided suggests two key variables: the color of the product and the customer's choice.

In variable specification, it is crucial to decide whether the variable is independent, dependent, or confounding. Here, product color is independent as it is the attribute being manipulated to observe an effect, while the choice is dependent on the color. Accurate specification of variables is critical for collecting meaningful and usable data.
Statistical Analysis
Statistical analysis is where the collected data is transformed into meaningful information. This process includes summarizing the data sets, inferring patterns, and testing hypotheses. In the context of our research question, statistical tools can calculate the correlation between product color and customer choice.

Insights such as which color is most popular or if color significantly influences choice can be revealed. When conducting statistical analysis, it's important to select the appropriate tests for your data type and research question, such as chi-square tests for categorical data or t-tests for comparing means.

Indicate whether we should trust the results of the study. Is the method of data collection biased? If it is, explain why. Send an email to a random sample of students at a university asking them to reply to the question: "Do you think this university should fund an ultimate frisbee team?" A small number of students reply. Use the replies to estimate the proportion of all students at the university who support this use of funds.

Indicate whether we should trust the results of the study. Is the method of data collection biased? If it is, explain why. Take a random sample of one type of printer and test each printer to see how many pages of text each will print before the ink runs out. Use the average from the sample to estimate how many pages, on average, all printers of this type will last before the ink runs out.

For the situations described. (a) What are the cases? (b) What is the variable and is it quantitative or categorical? Estimate the bending strength of beams by bending 10 beams until they break and recording the force at which the beams broke.

Employment statistics in the US are often based on two nationwide monthly surveys: the Current Population Survey (CPS) and the Current Employment Statistics (CES) survey. The CPS samples approximately 60,000 US households and collects the employment status, job type, and demographic information of each resident in the household. The CES survey samples 140,000 nonfarm businesses and government agencies and collects the number of payroll jobs, pay rates, and related information for each firm. (a) What is the population in the CPS survey? (b) What is the population in the CES survey? (c) For each of the following statistical questions, state whether the results from the CPS or CES survey would be more relevant. i. Do larger companies tend to have higher salaries? ii. What percentage of Americans are selfemployed? iii. Are married men more or less likely to be employed than single men?

State whether the data are best described as a population or a sample. A questionnaire to understand athletic participation on a college campus is emailed to 50 college students, and all of them respond.
