Answer: 2, 2, 3
Frequency refers to the number of times an event or value occurs, and in this case, the frequency of the Temperature is the amount of times a number appears in the data.
A grouped frequency table is a frequency table with data organised into smaller groups, often referred to as sets or classes. They can be very useful when we are working with large data sets.
From 101-106 the frequency is 2, because in the data, 104 and 104 fits into the class
From 107-112, the answer is 2, because in the data box to the left, there are two numbers ( 112, 107) that fit into class
From 113-118, you should write the frequency as 3, because the numbers to the left ( 114, 117, 118) fit into the data set.
