Question

If you want to conduct a practical study that finds

the average height of a Great Dane, which of the
following would be a good method of collecting a
population sample?

Answer 1

• Random sampling [ Probability and statistics method ]

Explanation:

• This method is easier and saves time.

By probability, a person whose height is to be recorded will be chosen randomly. This will be done on approximately 40% members.

By statistical step, we'll feed results into distribution table. Then we'll find the mean height.

`{ \boxed{ \rm{mean \: height = ( \sum \: f(n))/(n) }}}`

• f of n is product of frequency and respective height bracket

• n is the number of samples.
