  • Learning goals
  • Representing sets of data
  • Homework

Slide 1 - Tekstslide

Learning goals 
At the end of this lessons I can:
  • Sort data in qualitative or quantitative data
  • Sort quantitative data in discreet or continuous data
  • Draw and read a stem-and-leaf diagram
  • Calculate the measures of central tendency of any data

Slide 2 - Tekstslide

Statistics

Slide 3 - Woordweb

Representing sets of data
Qualitive data: data describing a certain characteristic

Quantative data: data with a numerical value 


        Discrete data                                                   Continuous data
                                     

Slide 4 - Tekstslide

Representing sets of data
Qualitive data: data describing a certain characteristic
ex: color of each car passing by
Quantative data: data with a numerical value 


        Discrete data                                                   Continuous data
                                     

Slide 5 - Tekstslide

Write on one side of the whiteboard "qualitative" and on the other side "quantitative" .

Slide 11 - Tekstslide

Measures of central tendency
Mode: The value that occurs most often 

Median: The middle value (when the data is put in order)

Mean: The average for the dataset

Slide 12 - Tekstslide

Measures of central tendency
Median: The middle value (when the data is put in order)

n = amount of values  
When n = odd




2(n+1)
Median =           th value
n = 19

Slide 13 - Tekstslide

Measures of central tendency
Median: The middle value (when the data is put in order)

n = amount of values 

When n = even







Median =           th value

Take average of the middle values
2(n+1)
n = 30

Slide 14 - Tekstslide

Mode =



Median =
