\[Direct\; Method: x̅ = \frac{\sum_{i=1}^{n}f_i x_i}{\sum_{i=1}^{n}f_i}\] |

where f_{i }x_{i } is the sum of observations from value i = 1 to n And f_{i }is the number of observations from value i = 1 to n |

\[Assumed\; mean\; method : x̅ = a+\frac{\sum_{i=1}^{n}f_i d_i}{\sum_{i=1}^{n}f_i}\] |

\[Step \;deviation \;method : x̅ = a+\frac{\sum_{i=1}^{n}f_i u_i}{\sum_{i=1}^{n}f_i}\times h\] |

\[Mode = l+\frac{f_1 – f_0}{2f_1 – f_0 – f_2} \times h\] |

\[Median = l+\frac{\frac{n}{2} – cf}{f} \times h\] |
