Using and describing on Graphs and Charts

What types of graphs and charts are you familiar with? And what are they used for? ? ?

Before we can describe a graph/chart… Let’s graph a description! Ready to draw?

Draw • • A line graph A bar graph A pie chart A Venn diagram

A line graph is most for showing trends, and for identifying whether two variables relate to (or "correlate with") one another.

A bar graph shows relationships between different data series

A pie chart compares parts to a whole. It shows a percentage distribution.

A Venn diagram is a great method for conveying the amount of commonality or difference between distinct groups.

Draw a line graph to represent the following statements about customer numbers: 1 -The trend in customer numbers was upward. 2 -Customer numbers fluctuated slightly. 3 -There were considerable fluctuations in customer numbers. 4 -The number of customers fell dramatically 5 -Numbers fell steadily. 6 -There was a dramatic drop in customer numbers, and then numbers fluctuated wildly again.

More drawing… 7 -There was a downward trend in customer numbers. 8 -Customer numbers were erratic. 9 -There was a steady fall in customer numbers. 10 -Customer numbers plunged. 11 -The trend was flat. 12 -There was a slight dip in customer numbers. 13 -Customer numbers dipped suddenly. 14 -Customer numbers reached a peak.

Draw a bar graph to show relationship in the descriptions below: 1. I had Sunday off, so no work. 2. My work increased sharply on Monday because I had two meetings with new clients and one class. 3. It plateaued on Tuesday as I had the same amount of meetings and classes. 4. My work decreased sharply on Wednesday because although I still had one class, I had no meetings 4. It stayed the same on Thursday because I had no classes – just one meeting. 5. It peaked on Friday because I had two classes and three meetings. 6. It decreased slightly on Saturday because I only had two meetings and two classes.

Draw a pie chart that shows the relative size of populations of countries of the European Union in 2007, as described: • We can see that the country with the largest population was Germany with 17 % of the European Union’s population. • We can also see that the second largest population was that of France with 12 % of the population. • You can see that the four largest countries (Germany, France, the United Kingdom and Italy) together make up more than half of the European Union’s population. • We do NOT know from this chart which country has the smallest population because the 21 smallest countries are included in one group. • The twenty-one least populated countries of the European Union make up nearly 30% of the population. • Although Poland shows the smallest population percentage, we know that 21 other countries have populations smaller than Poland’s.

Verbs for describing how data have changed: • to increase, to go up, to rise, to climb • to remain (unchanged), to be steady, to plateau • to decrease, to go down, to decline, to drop Adverbs • sharply, dramatically, significantly • steadily, gradually • slightly, slowly Adjectives • sharp, dramatic, significant • steady, gradual • slight, slow You can describe the changes presented in the graph in two ways: • From October to December, attendance decreased steadily or • From October to December, there was a steady decrease in attendance.
