Comparing categorical data + numerical data

Schedule: 

• Learning goals
• Comparing categorical data 
• Numerical data/outliers 
• Work on your own data

Learning goals 

At the end of this lesson I can:

•  Compare 2 sets of (categorical) data
• Draw a tall and frequency table for numerical data 
• Find outliers 

Comparing categorical data

- Compare the modes of the data sets

- How does the difference in the total amount of students influence the graph?

Numerical data

Numerical data = data which is in number form

in the survey I asked:

- your gender

- Your height

- Your travel time

- Your favorite subject

- The continent you lived in before the Netherlands

6 children is a outlier 

Outliers are much larger or smaller that most of the data

Class data (categorical)

1. Go to ManageBac > Files > Unit 6 probability and statistics > MP2F data and MP2A data

2. Choose one of the following topics: Favorite subject, continent you lived in before the Netherlands, Languages spoken

3. Draw a frequency table including the data from both MP2A and MP2F

4. Create a side-by-side column graph comparing the data 2 classes 

5. Compare the modes of the classes 

6. Done? Repeat steps 2-5 for a different topic.
