Finding the Median for Grouped Data

Sum of frequency before the median class

Lower class boundary of the median class (correct)

Size of the class interval

Frequency of the median class

$Mode = L + \left(\frac{\Delta1}{\Delta1 + \Delta2}\right)h$ (correct)

$Mode = L + \left(\frac{\Delta1}{h}\right)$

$Mode = L + \left(\frac{\Delta1 + \Delta2}{2}\right)h$

$Mode = L + \Delta1h$

$x_1$ multiplied by $a$ plus $x_2$ multiplied by $a$ (correct)

$x_1$ and $x_2$ values

A calculation error

$a$ multiplied by sum of all observations
