Question 5) Select the correct statement below. O We should use a randomized block design using a two-way ANOVA model without an interaction term between Solution and Day and with a blocking factor for Days. O We should use a randomized block design using a two-way ANOVA model without an interaction term between Solution and Day and with a blocking factor for Solution. O We should use a randomized block design using a two-way ANOVA model without an interaction term between Solution and Day and with a blocking factor for Bacteria growth.
please provide explanation aswell if possible,
thank you so much!
The main objective of an ANOVA (one-way) is to compare the means of more than two means to identify whether there is a statistically significant difference in the means. Additionally, for two-way ANOVA, three or more populations can be compared based on the means of two different factors.
Moreover, for ANOVA all observations used are independent. But when measuring some observations on the same individuals, then they are no longer independent and therefore, ANOVA cannot be used anymore.
In this case observations are taken for four days to measure of effectiveness (bacteria growth rate after using the solution) for each day when solution type is given.
