 Example: Info graphic
 

Testing -> checking if the processing is working
E.g. Excel spreadsheet with functions

 Validating -> checking input data

 Completeness -> all charts labelled and explained and answers hypothesis

 Reliability -> sources are identified

 Presentation -> engaging, appropriate topic, pleasing to the eye

 Functionality -> does it accurately, depicts the data

 

 

Framing an Investigation
 

a)   Starts with  theory or  question

Eg. Do girls use social-media more than boys?

b)  Write a hypothesis

Eg. Girls will use social media than boys

 
c)    Investigate by collecting evidence to test hypothesis

Eg. Question/Survey

d)  Interpret Data

Eg. Compare girls with boys for each question (categories/section/group results) look at the data for how it should be graphed

e)   Accept or Reject data

Eg. Report on findings
