Your three friends are trying to limit the number of times they check their social media

on their phones, so they all decide to individually record the number of times they check

their social media a day for the course of one week (Monday-Sunday).

Friend A checked their social media (on their phone) two times a day during the course

of the week, while Friend B checked their social media on their phone three times every

other day over the course of the week (Monday-Sunday).

Friend C checked their social media on their phone 6 times a day for the first four days

(Monday-Thursday) of the week, and then they checked their social media on their

phone 7 times a day in the last three days of the week (Friday-Sunday).

Without using the formula discussed in class, list your three friends in order from least to

greatest standard deviation.
