Example 2 The table below gives the percentage distribution of female teachers in the primary schools of rural areas of various states and union territories (U.T.) of India. Find the mean percentage of female teachers by all the three methods discussed in this section. Mean(π‘₯ Μ…) = a + h Γ— (βˆ‘β–’π’‡π’Šπ’–π’Š)/(βˆ‘β–’π’‡π’Š) Where a = assumed mean h = Class interval Also, βˆ‘β–’π’‡π’Š = 35 βˆ‘β–’π’‡π’Šπ’–π’Š = βˆ’36 Putting values in formula Mean(𝒙 Μ…) = a + h Γ— (βˆ‘β–’π’‡π’Šπ’–π’Š)/(βˆ‘β–’π’‡π’Š) π‘₯ Μ… = 50 + 10 Γ— (βˆ’36)/35 π‘₯ Μ… = 50 – 10.29 𝒙 Μ… = 39.71 Therefore, mean percentage of female teachers is 39.71
