પ્રયોગમાં સાદા લોલકના દોલનના સમયગાળાની યાદ

$T\,\, = \,\,\frac{{2.63\,\, + \;\,2.56\,\, + \;\,2.42\, + \;\,2.71\,\, + \;2.80}}{5}$

$ = \,\,\frac{{13.12}}{5}\,\, = \,\,2.624\,\, \cong \,\,2.62$

$\begin{gathered}
  \left( 1 \right)\,\,2.62\,\, - \,\,2.63\,\, = \, - 0.01 \hfill \\
  \left( 2 \right)\,\,2.62\,\, - \,\,2.56\,\, = \,\, + 0.06 \hfill \\
  \left( 3 \right)\,\,2.62\,\, - \,\,2.42\,\, = \,\, + \;\,0.20 \hfill \\
  \left( 4 \right)\,\,2.62\,\, - \,\,2.71\,\, = \,\, - 0.09 \hfill \\
  \left( 5 \right)\,\,2.62\,\, - \,\,2.80\,\, = \,\, - 0.18 \hfill \\
