STATISTICS 2º ESO

TITLE: STATISTICS

This unit is aimed at students of 2nd ESO of the subject of mathematics.

 

Learning outcomes

 

- Get the count of a number of data to form a table and study their properties.

-  Distinguish between absolute and relative frequency of a data, and calculate both frequencies.

-  Plot a dataset.

-  Interpret graphical statistics.

-  Determine the arithmetic average of a set of data.

-  Calculate the average and mode of a data set.

 

Subject Content

 

-  Count data and build tables.

-  Absolute frequency and relative frequency.

-  Graphical representations.

-  Mean, median, mode and range.

 

 

Organization and classdistribution: 

The unit will take about 10 sessions.

Each concept is explained using the document Statistics 2nd ESO, where necessary vocabulary to keep the unit is included. It also includes examples and introductory activities. https://drive.google.com/file/d/0B1yhfA4BI9YSOFJHc3BWeEw1bDA/view?usp=sharing

And then will be worked to the proposed activities.

Many of them can be worked in groups of 2 or 4 and others can be made with whole class on the whiteboard. The last two sessions will be reserved for the final project.

Sessions:

·         Sessions 8 and 9: Final project.

A pharmaceutical company has developed a new drug and wants to test it and see how fast its effects are. 

For that reason, they have given the drug to 300 patients and have recorded how many weeks they needed to get better.

https://docs.google.com/file/d/0B8TuD_xruuOVME1VRVB3VjYxNms/edit?pref=2&pli=1

Build a complete frequency table, a bar graph and a pie chart using a spreadsheet document. 

 Create a text document to present your research. 

Put a title and your name on the top and then copy the table and the graphs into in. On the second page, copy the following questions and anwer them. 

Questions:

1. What was the most common number of weeks to recover? How do we call that?

2. Complete this sentence: "Half the patients of the group were cured after ..... weeks". How do we called that number?

3. Find the average number of weeks to recover.

4. How many patients were cured after the first month?

5. What percentage of the patients took more than 10 weeks to recover?

Evaluation:

Evaluation criteria:

·    Obtain information about a specific feature population, organize in tables and graphs and draw conclusions.

·    Obtain and interpret statistical parameters such as mean, mode or range from discrete distributions of data arranged in tables.

Evaluation instruments:

-          The daily work of the student.

-          The final test of the unit.

-          The final project.
