Activity Experimental Research Design Directions: Below is a problem/situation, read and analyze it carefully and give the layout of the experimental research design being asked. Situation: A biology class wanted to study the effect of different materials on the melting rate of ice. They placed pieces of ice, each with a mass of 10g, onto trays. Group 1 was covered in plastic, group 2 was covered in paper, group 3 was covered in aluminum, and group 4 remained uncovered. Each piece of ice was allowed to melt for 15 minutes. Then the final mass of the ice, minus the melted water, was recorded at the end of the experiment. Q1. What experimental research design was used in the study? Present the layout identifying the different groups involved. Give a one-sentence justification. Ans. Q2. Illustrate an experimental layout for each experimental research design below (Use the above-mentioned situation/study.) Single Group Design Control - Group Design Parallel Design report if THE ANSWER IS WRONG answer need ASAP

Answer:

1.There are three primary types of experimental design: Pre-experimental research design. True experimental research design. Quasi-experimental research design.

2.The layout of an experiment refers to the physical arrangement of experimental units in space. Experimental layouts can be either completely randomized or blocked arrangements.
