collection of primary data

answered on 19-Sep-24 19:37

is not collection of data from enumerators considered a secondary source?

latest answer

Key difference between primary and secondary sources of data collection is who collects the data and the purpose of the data collection. Primary data is collected directly by the enumerator to answer a specific research question.Secondary data was collected by someone else for a different research project or to answer a different research question and you use it for some project.

There is one question: Prove that 33 ! is divisible by 2^15. What is the largest integer n such that 33! is divisible by 2n?

latest answer

In terms of prime factors 33! can be written as 2^a ⋅ 3^b 5^c ⋅ 7^d … (33!)=33/2+33/2^2+33/2^3+33/2^4+33/2^5 =16+8+4+2+1=31 Hence, the exponent of 2 in 33! is 31. ∴ Largest value of n is 31.
