To propose an experimental design of the type Design in Complete Blocks at Random (DBCA, DCL or DGCL) completely on any experiment that can be done with materials at home.

(Here are some examples: *the requested example should be different from these, they are just a guide*

If 4 pins are placed on a sloping surface, the time it takes to slide down the surface may change, depending on the surface material. We want to see if really 3 different surfaces (of 3 different materials) make the time it takes for the bolincha to reach the end differ. For this, an experimental design is proposed. It is preferred to use the person who will drop the ball on the surfaces as the block factor, since 3 different people would do this. We want to compare 3 different types of land to plant beans, what happens is that 3 different people are going to plant the beans, for this reason the person who will plant is used as a block factor and the factor of treatment or interest will be the type of land . As a response variable, the height of the bean plant in a given time could be used. )
