I am comparing Google search data between 3 cancers as part of a small project, and have the attached file generated from Google trends data. How do I see if the searches for a particular cancer are going up with time?, and if so is the difference in trend significant? Next, can I compare trends between cancers C, P and L (from the attached file)?
The first issue I see with this request is that it looks very much like a homework assignment. Please excuse my assumption if it is not.
The second issue, is that your "Month: column has been input as a character column. For any analysis across time this column needs to be changed to being numeric.
The code below adds a numeric date column (assumes 1st of every month) and creates a graph using Graph Builder.
dt = data table("CancerIS_JMP"); dt << New Column( "Month Dt", Numeric, "Continuous", Format( "ddMonyyyy", 10 ), Input Format( "ddMonyyyy" ), Formula( Informat( :Month || "-01", "yyyy-mm-dd" ) ) ); gb = dt << Graph Builder( Size( 530, 452 ), Show Control Panel( 0 ), Variables( X( :Month Dt ), Y( :IS ), Overlay( :Cancer Type ) ), Elements( Line( X, Y, Legend( 15 ) ), Points( X, Y, Legend( 16 ) ) ) );
You can do a visual inspection to see there are any upward trends. If you need something more quantitative you could fit a model.
