What is the difference between mean and range?
Mean is the average of all the numbers in the given data. It is the best way to analyze the central tendency of the data. It uses all the data points. Range is the difference between the largest number and the smallest number. It gives a broad idea about the spread of the data. It only uses two points.
What is the interquartile range?
The interquartile range (IQR) is the difference between the upper quartile $(Q_3)$ and the lower quartile $(Q_1)$. $IQR = Q_3 \;−\; Q_1$
What are quartiles in statistics?
Quartiles are the points (a set of three points) that divide the data into four equal parts or quarters. The first, second, and third quartile is represented by $Q_1,\; Q_2$, and $Q_3$ respectively.

I’m helping my kids with their homework. Does anyone know the answers for b and c? I know range means from…to…, but the provided answers are 123 degrees and 235 degrees
You are looking for either:
A closed interval: $[a,b]$ represents the set of all real numbers greater or equal to $a$ and less or equal to $b$.
A integer interval: $[a\ldotp\ldotp b]$ represents all integers in between $a$ and $b$. ($[1\ldotp\ldotp 5] = \{1,2,3,4,5\}$)
This is a useful wikipedia reference.
It is important to make the distinction between whether or not a particular endpoint is included. Use ( or ) to exclude and [ or ] to include.
For instance
$$(a,b) \;\;\Rightarrow \;\; \{x\in\Bbb R:a<x<b\}$$ $$[a,b] \;\;\Rightarrow \;\;\{x\in\Bbb R:a\le x\le b\}$$ $$\{a..b\} \;\;\Rightarrow \;\;\{x\in\Bbb Z:a\le x\le b\}$$
