Answer 1

Hint: The data collected by the researcher himself through interviews, observations, surveys etc. is the primary data whereas secondary data is the data collected by someone collected by someone else earlier and can be accessed through sources like publications,journals, books etc.

Complete step-by-step answer:
I.Number of trains that pass through Thane railway station.
→ Secondary data.
     Reason:
This information can be collected by the railway officials as the researcher himself won’t count the trains.

II.Number of Barbie dolls available in different Barbie stores in Mumbai.
→ Secondary data.
     Reason:
Researchers cannot go from store to store to get the same information, instead will collect from a source.

III.Number of foodies visit the zomato website
→ Primary data.
     Reason:
Number of people visiting the website changes, the researcher himself needs to keep an eye on day to day statistics.

IV.Number of people visit museums during summer.
→ Primary data.
     Reason:
As it is talking about only 1 museum, the researcher himself has to keep the record of people visiting during summer.

V.Number of musicians in Mumbai city who know both guitar and drum.
→ Primary data.
     Reason:
Number of such people can change on a daily basis, hence the researcher is required to keep the respective statistics up to date.

Note: Whenever the words like ‘our’, ‘here’, ‘my’ etc. are used, the data is always primary.Data with words like ‘obtained’, ‘extracted’ etc. are always secondary.
