Clear my choice An experiment is to be conducted to determine the effect of temperature on the adhesive strength of C-glue. The glue will be applied to a material at either 10 C, 20 C or 30 C. The experiment will be conducted separately for two different types of material (metal and plastic), as the effect of temperature is expected to differ for the two materials. Ten pieces of metal and ten pieces of plastic will be tested for each treatment. i. What is the appropriate type of experimental design that should be used? ii. What are the experimental units? iii. What is/are the factor(s) under investigation? iv. What are the factor levels? v. What are the treatments to be applied? vi. Is there a blocking variable? If so, what is it
