Introductionme13698642cee62f2_1528450127855_0Introduction

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

A quick contest in pairs. One person makes a tabletabletable with data about the number of hours of sleep in the last week and the other person presents this data in the form of a horizontal bar chartbar chartbar chart. Then they change roles.

Procedureme13698642cee62f2_1528446435040_0Procedure

Students analyse the example:

At the end of the schoolyear, students of classes 1A and 1B wrote a test from the Polish language. Results they obtained are presented in the bar chartbar chartbar chart.

[Illustration 1]

Task
Observe how data presented in the bar chart can be presented using the percentage bar chart.

[Interactive illustration]

Students’ conclusions:

- The most common form of presenting statistical data is a table.
- Graphical presentation of statistical data is making various types of graphs.
- A graph can be a vertical or horizontal bar chart, a percentage diagram, a pyramid of population, a stem‑and‑leaf diagram etc.me13698642cee62f2_1527752263647_0- The most common form of presenting statistical data is a table.

Individual task contest.

Students do the contest tasks. They can look for necessary information in available knowledge sources, for example the Internet.

They can go to the next level after verifying results from the previous level.

Three students with the best time score get the highest marks, three following – second highest marks.

Task
In the bar chartbar chartbar chart there are results of the waste paper collection in a school, in classes 1–3.

[Illustration 2]

a) Present this data in a horizontal bar chart, with the division for first, second and third classes.
b) How many kilograms more did class I b collect compared to classes who got the second and third place?
c) What percentage of waste paper collected in all school is waste paper collected by class IIIa? Round the number to 1%.
d) Present this data in a pie chart with division for first, second and third classes.me13698642cee62f2_1527752256679_0a) Present this data in a horizontal bar chart, with the division for first, second and third classes.
b) How many kilograms more did class I b collect compared to classes who got the second and third place?
c) What percentage of waste paper collected in all school is waste paper collected by class IIIa? Round the number to 1%.
d) Present this data in a pie chart with division for first, second and third classes.

Task
In the tabletabletable there are results about the number of books read in the first three months of the year.

[Table 1]

a) Present this data on one horizontal bar chartbar chartbar chart.
b) Present data about the amount of books read in three months on a pie chartpie chartpie chart.

Task
Present the structure of gender and age of the Polish population this year using the pyramid of population. Look for necessary information in available knowledge sources.

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

An extra task:
Look for information about presenting data in the form of a stem‑and‑leaf tabletabletable. Present information about the height of students from your class using this method.

Lesson summaryme13698642cee62f2_1528450119332_0Lesson summary

Students do the revision exercises.

Then together they sum‑up the classes, by formulating the conclusions to memorise.
