Statistics - Grade 5


Video lessons, examples and solutions to help Grade 5 students learn about data handling.




 


In these lessons, we will learn how to differentiate between first-hand and second-hand data. We will learn how to draw and interpret double bar graphs.


First-Hand Data and Second-Hand Data

Differentiate between first-hand and second-hand data.
First-hand data is data that you collect yourself.
Second-hand data is data that is collected by someone else.

First-Hand Data
• Data collected by the researcher (in school, this is the student)
• Observations, surveys, experiments
• Student primary source
• Questions created should help give more precise answers

Second-Hand Data
• Data collected by others and used for secondary analysis
• Found in news, Internet, statistics
• Student not part of data collections or questioning
• Can create questions based on data

First hand vs second hand data.





Double Bar Graph

A double bar graph is best used to show how two sets of data are different or alike.

In a double bar graph:
• Each set of data must use the same scale
• All graphs must have a title, scale and legend.
• The order of colors must remain the same throughout.

An example is presented below. Five students in the class have been asked how many brothers and sisters they have.
