What is the maximum height of a bar in a relative frequency histogram? 1 100 no maximum number of data values

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

..

step-by-step explanation:

b.an increase in a causes b to decrease
