# Mean, Median, Mode

mean =

**
Median :** Median is the middle term in the collected data. In case of even number of terms, take average of middle terms.

median =

- L-lower limit of median class
- N-total frequency = âˆ‘
*fi* *h*-width of median class.- C-cumulative frequency upto class preceding median class
- f -cumulative frequency of median class

**Mode** : It is the value that occur most frequently or it is the value with maximum frequency.

mode = Ã— *h*

- L-lower limit of class certaining mode
*f*-maximum frequency_{i}*f*_{i}_{â€“1}-frequency preceding*f*_{i}*f*_{i+}_{1}*-*frequency just after*f*_{i}*h-*size of model class

# Points to be noted

- For asymmetric distribution : mean = medians = mode
- For normal distribution : mean â€“ mode

= 3(mean â€“ median).
