Five pendulum-period measurements are $2.63$ , $2.56$ , $2.42$ , $2.71$ and $2.80 s$ . Find the mean period in seconds.

Answer:

2.62

Solution:

$\sum_{i = 1}^{5} T_{i} = 13.12 s$

$\overset{ˉ}{T} = \frac{\sum _{i = 1}^{5} T _{i}}{5}$

$\overset{ˉ}{T} = \frac{13.12}{5} = 2.624 s$

$\overset{ˉ}{T} = 2.62 s$

Rounded to two decimal places.
