Mode Concept

Mode Concept

Mode means most frequent observation or observation occurring more frequently. There may be more than one mode; there may also be no mode for a data. In simple term observation with most number of frequencies is known as mode.

Mode for un grouped & Grouped Data

Mode for ungrouped data can be found by simpler observation. While mode for grouped data is found by a formula given below;

Mode for Grouped Data = l+       [fm-  f1]             x h

                                                   [fm-f1]+[fm-f2]

l=lower class boundary

h=class interval

fm = highest frequency

f1= previous class frequency

f2= nex class frequency

Mode Empirical Relationship Formula

Mode can be calculated by the following formula, it is important to remember that this formula will not work for the highly skewed or u shaped frequency distribution.

Mode = 3 median – 2 mean
