Secondary Data: Explanation

Secondary data is the data that has been previously collected for some other purpose and is readily available for researchers to use. The data collected on sex ratio from the census reports are considered secondary data because it has been previously collected by the government for the purpose of population statistics and is available for researchers to use for their own analysis.

Primary Data vs. Secondary Data

Primary data is the data that is collected by the researcher for a specific purpose. It is original data collected through observation, surveys, experiments, or other means. On the other hand, secondary data is the data that is collected by someone else for a different purpose, but it can be used by researchers for their own analysis.

Discrete Data vs. Continuous Data

Discrete data is the type of data that can only take on certain values, such as integers. For example, the number of children in a family is a discrete variable because it can only take on whole number values. On the other hand, continuous data is the type of data that can take on any value within a certain range, such as height or weight. The sex ratio data collected from census reports is neither discrete nor continuous data, as it represents the proportion of male and female population in a given area.

Conclusion

In conclusion, the data collected on sex ratio from census reports is considered secondary data because it has been previously collected by the government for a different purpose. It is neither discrete nor continuous data, as it represents the proportion of male and female population in a given area.

It is secondary data
Because The data is primarily collected through census
but we are using the data from the data already collected from census.So the data collected from census is primary data and our data is secondary data
