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.
Is using this data a reliable way to determine the average age of facial hair growth for human males around the world?
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.
