## What are the common types of quantitative data collection?

Although there are many other methods to collect quantitative data, those mentioned above probability sampling, interviews, questionnaire observation, and document review are the most common and widely used methods either offline or for online data collection.

**What is an example of continuous quantitative variable?**

Examples of continuous variables are body mass, height, blood pressure and cholesterol. A discrete quantitative variable is one that can only take specific numeric values (rather than any value in an interval), but those numeric values have a clear quantitative interpretation.

### What is quantitative research design?

Quantitative research design is aimed at discovering how many people think, act or feel in a specific way. Quantitative projects involve large sample sizes, concentrating on the quantity of responses, as opposed to gaining the more focused or emotional insight that is the aim of qualitative research.

**What is continuous variable in quantitative research?**

Continuous variables are variables that can take on any value within a range. Continuous variables are also considered metric or quantitative variables, where the variable can have an infinite number or value between two given points. Continuous variables are often measured in infinitely small units.

#### Why do we use quantitative research design?

Quantitative Research is used to quantify the problem by way of generating numerical data or data that can be transformed into usable statistics. It is used to quantify attitudes, opinions, behaviors, and other defined variables – and generalize results from a larger sample population.

**What are the characteristics of quantitative research design?**

Characteristics of Quantitative Research

- The data is usually gathered using structured research instruments.
- The results are based on larger sample sizes that are representative of the population.
- The research study can usually be replicated or repeated, given its high reliability.

## What is an example of quantitative continuous data?

Example of Quantitative Continuous Data The data are the weights of backpacks with books in them. You sample the same five students. The weights (in pounds) of their backpacks are 6.2, 7, 6.8, 9.1, 4.3. Notice that backpacks carrying three books can have different weights.

**Is grade level quantitative or qualitative?**

But in the U.S. for example they have A,B,C.. so you could say that there the grades is a qualitative variable. A finer categorization of the “level of data” is surely “nominal scaled”, “ordinal scaled”, “interval scaled” and “ratio scaled” (see more about this in wikipedia).
