How to find modal class with example

Finding the modal class from a grouped frequency table is actually quite easy to do. All you need to do is to look for the group that has the highest frequency. This is because the mode is the number that comes up the most times. Make sure you write the group down and not the frequency. If you do this you will not score any marks. In most exams finding the modal class will only be worth one mark as there is no working out to show. So just remember to look for the group with the highest frequency.

Let’s take a look at some examples that involve finding the modal class from a grouped frequency table.

Example 1

The frequency table shows the weights of some patients a doctors surgery. 13 people have a weight 60kg up to 70kg, 2 people have a weight 70kg up to 75kg, 45 people have a weight 75kg up to 95kg and 7 people have a weight 95 up to 100kg. Write down the modal class interval.

So all you need to do is look for the group that contains the highest frequency. There were 45 people who had a weight between 75kg and 95kg so this will be the modal group.

Therefore the modal class interval is 75kg up to 95kg.

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p
