What are the variables in a case study?

Definition: Variables are characteristics studied in research that can take on different values (e.g., weight, height, exposure to a substance, demographics (i.e., where you live, your ethnicity, how much income you have, medical background).

What is the importance of making a case study?

The most significant benefit of case studies is that they enable a holistic review. Unlike standalone research techniques which give more of a snapshot, eg surveys, a case study offers the opportunity for a researcher to use a range of tools on one subject.

What is areas of consideration in case study?


What is the first step in conducting a case study?

Case Studies: Case Study Definition and Steps

  • Determine the research question and carefully define it.
  • Choose the cases and state how data is to be gathered and which techniques for analysis you’ll be using.
  • Prepare to collect the data.
  • Collect the data in the field (or, less frequently, in the lab).
  • Analyze the data.
  • Prepare your report.

How does confounding variable affect the validity?

Confounding variables (aka third variables) are variables that the researcher failed to control, or eliminate, damaging the internal validity of an experiment.

How do you evaluate a case study?

Let’s look at what each step involves.

  1. Identify the most important facts surrounding the case. Read the case several times to become familiar with the information it contains.
  2. Identify the key issue or issues.
  3. Specify alternative courses of action.
  4. Evaluate each course of action.
  5. Recommend the best course of action.

What problems can confounding variables cause?

A confounding variable is an “extra” variable that you didn’t account for. They can ruin an experiment and give you useless results. They can suggest there is correlation when in fact there isn’t. They can even introduce bias.

What is a case study according to Yin?

Yin (2003) identifies three types of case studies: Descriptive: the case study is used to describe a particular phenomenon within its context. It can be used to expand on a particular theme unearthed by a survey. Explanatory: the case study explores cause-effect relationships, and/or how events happen.

What is a cross-case analysis?

An analysis that examines themes, similarities, and differences across cases is referred to as a cross-case analysis. Cross-case analysis is used when the unit of analysis is a case, which is any bounded unit, such as an individual, group, artifact, place, organization, or interaction.

What are the most important part of case study?

The 4 Essential Elements of a Great Case Study

  1. Showcase the Problems You Answered. The customer has come to you with a problem or need for you to solve and you knocked it out of the water!
  2. Tell The Story of Your Customers’ Experience.

Can confounding variables be controlled?

A Confounder is a variable whose presence affects the variables being studied so that the results do not reflect the actual relationship. There are various ways to exclude or control confounding variables including Randomization, Restriction and Matching.

How do you conduct a case analysis?

Writing a Case Study Analysis

  1. Read and Examine the Case Thoroughly. Take notes, highlight relevant facts, underline key problems.
  2. Focus Your Analysis. Identify two to five key problems.
  3. Uncover Possible Solutions/Changes Needed. Review course readings, discussions, outside research, your experience.
  4. Select the Best Solution.

What is the format for a case study analysis?

Introduction – Write an introduction where you identify the key problem and make a summary of the thesis statement in 1 or 2 sentences. Background Information – Include some relevant facts and issues and conduct research on the problem. Alternatives – Describe several alternatives and explain why some were rejected.

How do you identify variables in a study?

The variables in a study of a cause-and-effect relationship are called the independent and dependent variables.

  1. The independent variable is the cause. Its value is independent of other variables in your study.
  2. The dependent variable is the effect. Its value depends on changes in the independent variable.

What are the characteristics of case study method?

Characteristics of Case Study method

  • Under this method the researcher can take one single social unit or more of such units for his study purpose; he may even take a situation to study the same comprehensively.
  • Here the selected unit is studied intensively i.e., it is studied in minute details.

What is the important role of variables in mathematics?

In mathematics, a variable is a symbol which works as a placeholder for expression or quantities that may vary or change; is often used to represent the argument of a function or an arbitrary element of a set. In addition to numbers, variables are commonly used to represent vectors, matrices and functions.

How do you deal with confounding variables?

Strategies to reduce confounding are:

  1. randomization (aim is random distribution of confounders between study groups)
  2. restriction (restrict entry to study of individuals with confounding factors – risks bias in itself)
  3. matching (of individuals or groups, aim for equal distribution of confounders)

Is time of day a confounding variable?

This third variable could be anything such as the time of day or the weather outside. In this situation, it is indeed the weather that acts as the confound and creates this correlation.

How does confounding variable affects the validity of the study?

Confounding variables are common in research and can affect the outcome of your study. This is because the external influence from the confounding variable or third factor can ruin your research outcome and produce useless results by suggesting a non-existent connection between variables.

How important are variables in a research study?

While the variation of an independent variable will influence the variation of dependent variable, both variables give the study a focus. Dependent and independent variables are also important because they determine the cause and effects in research.
