• There is no perceivable difference between the products 

• There is a perceivable difference between the products 

• The products are of similar quality 

• The test was not conducted properly

In a paired comparison test, what does a high number of correct responses indicate?

• The samples are identical 

• The test method is invalid 

• The participants' preferences are being measured

• There is a significant difference between the two samples 

How can the reliability of a discrimination/difference test be evaluated?

• By comparing the test results with consumer acceptance data
