2 Countries Quiz Write down the name of the country as their flag appears on the screen some may be revision!
3 What country does this flag belong to?
4 What country does this flag belong to?
5 What country does this flag belong to?
6 What country does this flag belong to?
7 What country does this flag belong to?
8 Countries Quiz Answers List the countries in order of smallest to biggest population! 1. Japan 2. Ireland 3. Greece 4. New Zealand 5. Sweden 1. New Zealand 2. Ireland 3. Sweden 4. Greece 5. Japan
9 Glossary Statistic Data Discrete Data Continuous Data Demographics A fact or piece of data collected from a study A set of values or measurable quantities. Data that is counted. Data that is measured. Data relating to populations or certain groups
10 Bar Graphs A bar graph is a display of data using bars of different heights. This style of graph is a very good way of showing relative sizes, but does not show continuous data well. Bar graphs use a vertical and horizontal axis, with categories and measurements labelled on both. Usually, different colours are used for different bars to make the graph easier to read.
11 Reading Bar Graphs Answer the following questions about the graph below What does this graph show? Which city has the highest population density? How many people per square km live in this city? How many people per square km live in Seoul? Name one city that is less developed.
12 Creating Bar Graphs Collect data under a specific category. We will collect data from our class on the most popular fast food chain. Fast Food Chain KFC Subway McDonalds Hungry Jacks Dominoes Number of Votes KFC Subway McDonalds Hungry Jacks Dominoes
13 Pie Charts A pie chart shows relative sizes using pie slices within a circle. Pie charts are an easy way to identify different information quickly, but do not show continuous data. These graphs need a key to identify categories of data, and use distinctly different colours to make the chart easy to read. Pie charts are used to represent categories/groups.
14 Reading Pie Charts Answer the following questions about the graph below What does this graph show? Which continent has the highest population? What percentage of the world s population does this continent have? What percentage of the world s population does Australia have?
15 Line Graphs A line graph shows continuous data and, like a bar graph, uses a labelled vertical and horizontal axis. Bar graphs are useful to analyse patterns of change over time. They are created by plotting points on a graph and then connecting those points with lines. Line graphs are used to represent values that are not fixed, for example - measurements.
16 Reading Line Graphs Answer the following questions about the graphs below What do these two graphs show? Which country is predicted to increase the most in the future? In what year will rural and urban populations be equal? Which country had the highest population in 2010?
17 Creating Line Graphs Use the data from the table below. Plot the points on the graph and then connect them with lines. Remember to look at the temperature values before creating a range on your graph Day of the Week Monday Tuesday Wednesday Thursday Friday Top Temperature 28 o 29 o 32 o 35 o 30 o M T W T F
18 Population Pyramids A population pyramid shows population based on age and gender. Each gender is represented on one side of the pyramid (the horizontal axis) and age is represented in ascending order up the middle (the vertical axis). In simple terms, a population pyramid is two bar graphs flipped and placed side by side. Population pyramids are useful to study demographics of a country or city to analyse and identify patterns these statistics can tell us a lot about the appeal of a certain place.
19 Analysing Population Pyramids Answer the following questions about the graph below How old is the majority of the Australian population? Are the majority of 0-24 year olds male or female? How many year old males were there in 2014? What does this population pyramid suggest about Australia?
20 Creating Population Pyramids Use the population data from the table to create a population pyramid for Utopia. Age Group Male Female Male Female
A is one of the categories into which qualitative data can be classified.
