Hello all,
I am running my data through minitab using a Anova>general linear model and I can't figure out why my coefficients are not giving my any values for snails or white (in bold below) even though the equation is coding for this. From the graphs I have made it should be showing a significant difference with at least one of these factors.
To run this test I do this process:
Stat
ANOVA
General Linear Model
Fit General linear model ...
Response - Ingestion
Factors- Organism Colour
OK
I can't see where i'm going wrong so some insight will be much appreciated.
Factor Information
Factor Type Levels Values
Organism Fixed 3 Anemone, Shrimp, Snail
Colour Fixed 4 Black, Blue, Red, White
Regression Equation
Ingestion = 0.8532 + 0.606 Organism_Anemone + 0.119 Organism_Shrimp - 0.725 Organism_Snail
+ 0.415 Colour_black + 0.258 Colour_blue - 0.353 Colour_red - 0.320 Colour_white
Coefficients
