Step-by-step explanation:
ANOVA can be used in a construction industry whereby the construction or project manager is saddled with the responsibility of picking the most appropriate method of construction or materials to be used during construction in the face of two or more alternative options.

However, due to the possibility of differences in construction cost, and project duration. The construction manager may need to use an ANOVA test to determine the project duration of each method and if it is later revealed through the test that all the methods of construction will lead to the project being delivered on time as the client scheduled.
Then, the construction manager may then result to pick the least expensive alternative of the construction methods.
