Good morning!

  • Learning goals 
  • Describing and comparing data
  • Continue with your research

Slide 1 - Tekstslide

Learning goals 
At the end of this lessons I can:
  • Describe the shape of a set of data 
  • Compare multiple sets of data 
  • Research data 

Slide 2 - Tekstslide

What vocabulary could you use to describe a data set?

Slide 3 - Woordweb

What vocabulary could you use to describe a data set?

Slide 4 - Woordweb

What are the measures of dispersion?

Slide 5 - Woordweb

Measures of dispersion
Range: The difference between the highest and the lowest value if a data set 

Interquartile range(IQR): 
The difference between Q1 (quartile 1) and Q3 (quartile 3) of a data set
Data set: 
Range = 

Q1 = 

Q3 = 

IQR = 

Slide 6 - Tekstslide

Measures of dispersion
Range: The difference between the highest and the lowest value if a data set 

Interquartile range(IQR): 
The difference between Q1 (quartile 1) and Q3 (quartile 3) of a data set
Data set: 
Range = 

Q1 = 

Q3 = 

IQR = 
20-2 = 18
2(13+15)=14
2(5+6)=5.5
14-5.5 = 8.5

Slide 7 - Tekstslide

Measures of central tendency
Mean: The average of a data set
Mean = sum of all values/amount of values

Median: the middle value of a data set (when the data is in order)


Mode: The value in the data set that occurs most often 
Data set: 
1 2 3 3 4 4 5 5 5 6 7 

Find the mean, median and mode

Slide 8 - Tekstslide

Measures of central tendency
Mean: The average of a data set
Mean = sum of all values/amount of values

Median: the middle value of a data set (when the data is in order)


Mode: The value in the data set that occurs most often 

Slide 9 - Tekstslide

Describing data
Multimodal
Unimodal
No modal value
Bimodal

Slide 10 - Sleepvraag

Describing data 
No modal value:
there is no mode
Bimodal:
there are 2 modes
Multimodal:
there are more than 2 modes
Unimodal:
there is 1 mode

Slide 11 - Tekstslide

Describing data 
How is the data centered? 
- Centered on lower values? 
- Centered on higher values? 
- Evenly distributed? 
- Symmetrical?

Slide 12 - Tekstslide

Comparing data
- "On average, class 1 scored higher than class 2"
- " The IQR from both classes are very close. The middle 50% of both classes have a similar spread"
- "Both classes had no outliers. Nobody scored extremely high or low on the test"

Slide 13 - Tekstslide

Comparing data

Slide 14 - Woordweb

Take out your diaries

Slide 15 - Tekstslide

Continue with your research
1. Calculate the five point summary, IQR and outliers for both males and females. 
2. Describe the data for both males and females. 
3. Compare the male data with the female data. 
(4. Compare your data with the data of another group.)
