Question

A roofing company would like to implement a new method for giving estimates. The owner has narrowed his choice to three different methods. Since estimator variability is believed to be a significant factor in the overall cost estimate, each of the company's three job estimators is asked to give a cost estimate for a new roof using each of the three methods. The data will be analyzed using a randomized block design. What are the blocks in this study?
a. the roofing company
b. the estimators
c. the estimate method
d. the cost for a new roof

Answer 1

The estimators are the blocks in this study

Explanation:

An estimator is a law in statistics for estimating a calculation based on observed figures for a given amount, thereby differentiating the definition, the quantity of value and its consequence. There are estimators for point and time.

To order to measure the time, energy, equipment and function necessary to produce a commodity, constructing a building or provide a service, cost estimators must gather and analyse data. They typically work on a particular company or industry.

It can either be finite-dimensional (parametric and semi-parametric) or infinite-sized (semi-parametric / non-parametric).
