Maximum height of a bar in a relative frequency histogram ranges from
0<Height of bar in a relative frequency histogram≤1
So a) 1 is the correct answer.
So let me start from here , in frequency histogram on X axis we draw bars and on vertical axis we represent frequencies.
But in relative frequency histogram we represent bars on X axis but relative frequency on Y axis i.e vertical axis.
Let me start by taking an example.Consider 20 observations
Interval frequency Relative frequency
0-5 4 4/20
5-10 8 8/20
10-15 5 5/20
15-20 3 3/20
As you can see from above example the height of bar can't extend than 1.
and sum of all relative frequency=4/20 +8/20 +5/20+3/20 =1
