Lesson stages

Introductionmee4c6d11b33ecdef_1528450127855_0Introduction

The teacher introduces the subject of the lesson – presenting and interpreting statistical datastatistical datastatistical data obtained from various sources.

Proceduremee4c6d11b33ecdef_1528446435040_0Procedure

Students analyse the example:

A survey was conducted among students of the eighth grade, whether or not they liked the last set book they were discussing in the class. Students could answer: yes, no, I don’t know. Obtained results were presented in the tabletabletable.

[Table 1]

See how we can present data from the table using a bar chart.

Task
Students look for important information about applied forms of presenting statistical datastatistical datastatistical data on the Internet.

[Interactive illustration]

Student’s conclusions:

- The most common form of presenting statistical data is a table.mee4c6d11b33ecdef_1527752263647_0The most common form of presenting statistical data is a table.

- Graphical presentation of statistical data is making various types of graphs.mee4c6d11b33ecdef_1527752256679_0Graphical presentation of statistical data is making various types of graphs.

- A graph is made of the title, the area of a graph, a legend, that contains information about applied symbols, colours and source of data.

Students use obtained information in exercises.

Task 
Present data from the example in the form a percentage diagram.

Task 
In a certain school there was a contest for the class that reads the most books in the current schoolyear. Classes 6, 7 and 8 took part in the competition. After finishing the contest, organizers prepared results in the form of a tabletabletable and presented the winners.

a) Present data on a vertical bar chartvertical bar chartvertical bar chart, with division for all classes.

b) Present data on a horizontal bar charthorizontal bar charthorizontal bar chart with division for sixth, seventh and eighth classes.

c) How many books were read in all 6, 7 and 8 classes in the current schoolyear?

d) Which class read the fewest books?

e) Which class among the sixth classes read the fewest books?

f) Did 8 classes together read more books than half of all books read by 6, 7 and 8 classes in the current schoolyear?

Task 
Data about height of students in the class was presented on a pie chartpie chartpie chart.

[Illustration 1]

Knowing that there are 20 people in the class, draw a bar chart for this data.

Task 
Look for information about 10 longest rivers in Europe on the Internet. Present obtained data in a table and make a bar chart.

The teacher sums‑up students’ work. The teacher rewards students who gave most accurate solutions with highest mark.

An extra task:
Make a questionnaire in your class about eyes’ colour. Present data in the form of a pie chartpie chartpie chart.

Lesson summarymee4c6d11b33ecdef_1528450119332_0Lesson summary
