## What data is used for correlation analysis?

It is a statistical-based, and thus, mathematics-based information analysis technique. It consists of analysing the relationship between at least two variables, e.g. two fields of a database or of a log or raw data. The result will display the strength and direction of the relationship.

**What is an example of a correlation analysis?**

Example of correlation analysis An increase in one variable leads to an increase in the other variable and vice versa. For example, spending more time on a treadmill burns more calories. Negative correlation: A negative correlation between two variables means that the variables move in opposite directions.

### What is an example of a data set?

A data set is a collection of numbers or values that relate to a particular subject. For example, the test scores of each student in a particular class is a data set. The number of fish eaten by each dolphin at an aquarium is a data set.

### How do you create a data set?

- Create Dataset. Navigate to the Manage tab of your study folder. Click Manage Datasets.
- Data Row Uniqueness. Select how unique data rows in your dataset are determined:
- Define Fields. Click the Fields panel to open it.
- Infer Fields from a File. The Fields panel opens on the Import or infer fields from file option.

**What is a good data set?**

A good data set is one that has either well-labeled fields and members or a data dictionary so you can relabel the data yourself. Think of Superstore—it’s immediately obvious what the fields and their values are, such as Category and its members Technology, Furniture, and Office Supplies.

## What do data sets look like?

A dataset (example set) is a collection of data with a defined structure. Table 2.1 shows a dataset. It has a well-defined structure with 10 rows and 3 columns along with the column headers. This structure is also sometimes referred to as a “data frame”.

## What are the five examples of data?

Solution:

- Number of houses in our housing society.
- Monthly grocery expenses of our home.
- Number of people who have used e-services of the state govt. over a year.
- Number of students who have enrolled for the Math Olympiad in our school.
- Population increase over the decade in our city.
