\(\overline{s}=\left(0,649+0,651+0,654+0,653+0,65\right):5=0,6514\)
\(\Delta s_1=\left|s_1-\overline{s}\right|=0,0024\)
\(\Delta s_2=\left|s_2-\overline{s}\right|=0,0004\)
\(\Delta s_3=\left|s_3-\overline{s}\right|=0,0026\)
\(\Delta s_4=\left|s_4-\overline{s}\right|=0,0016\)
\(\Delta s_5=\left|s_5-\overline{s}\right|=0,0014\)
\(\Rightarrow\overline{\Delta s}=\left(\Delta s_1+\Delta s_2+\Delta s_3+\Delta s_4+\Delta s_5\right):5=0,00168\)\(\)
Tương tự \(\overline{t}=3,514;\overline{\Delta t}=0,0168\)
\(\delta s=\dfrac{\overline{\Delta s}}{\overline{s}}.100\%=\dfrac{0,00168}{0,6514}.100\%=0,26\%\)
\(\delta t=\dfrac{\overline{\Delta t}}{\overline{t}}.100\%=\dfrac{0,0168}{3,514}.100\%=0,48\%\)
Kết quả đo : \(s=\left(\overline{s}\pm\overline{\Delta s}\right);t=\left(\overline{t}\pm\overline{\Delta t}\right)\)
