Is using this data a reliable way to determine the average
age of facial hair growth for human males around the world?
a college student conducts a survey to find out the average
age at which human males start to grow facial hair. the
student asks each subject of the survey how old he was in
months) when he first noticed hair on his face. six boys from
a local high school were surveyed, and the average value
found is 148 months.
no, because this is a small number of data points from
just one area, not the whole world,
no, because the data was measured in months, but most
scientists measure data in seconds.
yes, because six data points is more than enough to
make a graph and find a trend.
yes, because males grow facial hair at different ages, and
this study is finding the average age
