Give the formula for estimating mode in case of continuous series. |
|
Answer» Solution :The following formula is used to calculate the exact value of the MODE in case of continuous series after finding the modal CLASS. `Z=l_(1)+(f_(1)-f_(0))/(2f_(1)-f_(0)-f_(2))xxi` Here , Z= Value of the mode , `l_(1)` = LOWER LIMIT of the modal class , `f_(1)` = The frequency of the modal class , `f_(0)` = The frequency of pre- modal class , `f_(2)` =Frequency of the next higher class or post - modal class , i = Size of the modal group. |
