Unformatted text preview: 1.1*suggested) Number of treatments 8 Number of replicates 3 Number of measurements per replicate 1 Total number of observations 24 Amount of time planned for data collection 4 hours Controlled variables given as “Variable (value)” Curing time (7 or 14 days), cement type (type 1), curing temperature (60-80°F), strength tester (will use machine) Blocking variable, if used (not required) Treatment- three members will apply one replicate of each treatment to save time Important sources of experimental error not addressed by the experimental design: Accuracy of compression test- the machine is accurate to 10psi, so results could be inconclusive because of this. Describe how randomization will be used: We will both apply the treatments in random order as well as test the cylinders in random order....
