R Squared = .565 (Adjusted R Squared = .369) We find there is no significant difference between blocks and treatments since its significant value 0.750 is greater than 0.05 We find out there is a significant difference between treatments(urgents) since 0.007 significant value is less than the p-value of 0.05. Thou we could not run the post-hoc test since we had 2 treatments. We find there is a significant difference between the blocks(concentration) as its significant value is 0.02 is less than the p-value of 0.05 thus we run the LSD tests to determine the difference Post Hoc Tests concentration MULTIPLE COMPARISONS observation LSD (I) concentration(J) concentrationMean Difference (I-J)Std.
