What is the purpose of a side-by-side column graph?
To compare two sets of data.
What is Range?
The range is the difference between the highest and lowest number.
What is Data?
Information we collect
What is mode?
The mode is the number that appears the most often in a set of numbers.
What is discrete data?
Discrete data is data that can be counted and uses whole numbers only.
What is the title of the graph for?
To tell us what the graph is about.
Give one example of a good question for collecting data on cars.
What is your favourite car? What type of car do you drive?
Why do we collect Data?
To answer questions / understand things / make decisions.
What is median?
The median is the middle number in a data set when the numbers are in order from smallest to largest.
What is continuous data?
Continuous data is data that can be measured and can include decimals.
Which graph would you use to show changes over time?
A line Graph
What is the range: 8, 15, 3, 22, 15, 9, 27, 3, 18, 12, 15, 6, 30, 9, 21

What is the first thing you do when working with a data set?
Order them form smallest to largest.
What does shape mean when describing a graph?
Shape tells us how the data is spread on a graph.
column, side-by-side, line graphs
What is a broken axis?
A broken axis is when part of the scale on a graph is skipped.
What graph will you use to show the growth of a plant?
Line Graph
What is a side-by-side column graph?
A side-by-side column graph shows two or more sets of data next to each other so we can compare them easily.
What is the mode: 3, 4, 7, 13, 27, 45, 3, 2, 7, 87, 44, 5, 2, 32, 66, 13, 12, 3, 7, 3, 4, 7

How do we find the range?
Largest value - lowest value
Why might someone use a broken axis on a graph?
So the graph can fit large numbers or make changes look bigger or smaller.
Find the range and median - 18, 42, 27, 35, 50, 23, 31, 45, 29, 38
Range - 32
Median - 33
Find the mode and median: 8, 15, 3, 22, 15, 9, 27, 3, 18, 12, 15, 6, 30, 9, 21
Median: 15 Mode: 15
What is the median? 14, 12, 66, 32, 11, 5, 6, 7, 11, 5, 14, 13, 11, 66, 73, 14, 10, 7, 4
