Disadvantages Of Completely Randomized Design

In our Penny Lab, we wanted to extend what we were told to do with experimental design. We’re doing this because we wanted to prove what he thought our hypothesis had been, and a hypothesis can not be true unless it can be tested. We investigated what variables made the Penny Lab easier, or harder. As a class we decided to investigate variables like, dropping the penny from the same height, and applying the same pressure to the penny for each drop. But first we had to know what variables were, and which variables we needed to use in the experiment. The variables were, the independent variable, dependent variable, the experimental group, and the control group. We investigated this to show how much water a penny could hold, but we introduced

Describe the experimental method, state its advantages and disadvantages, and distinguish between independent and dependent variables.

| Validity of experiments are normally high as the variables are controlled except for the variable being tested.

As a group we encountered several possible errors throughout the experiment. Blunder error is a common error than can occur.

Participants were exposed to five experimental conditions (different types of labels) and asked to complete two tasks (“Pair-wise comparison of foods” and “Virtual grocery: Envisaged daily food consumption”). The experiment was monitored by 30 interviewers

3.     What are the advantages and disadvantages of an experimental design in an educational study?

The compiled data was used to form population A of the experiment, while population B was predetermined and provided by the instructor. Research was conducted using primary sources and data collected in order to locate evidence supporting the hypotheses.

1Split Testing: Experiments with two variables, one controlled and one varied; also known as A/B testing.

Each of these tests involves two or more treatments: 1) controls to provide standards for comparisons, and 2) unknowns to be identified. The unknown solution may or may not contain the substance that the investigator is trying to detect. Only a carefully conducted experiment will reveal its contents. In contrast, controls are known solutions used to validate that the procedure is detecting what is expected and nothing more. During this laboratory, we will compare the unknown solution's response to the test procedure with the control's response to that same

Controlled variable - The size of the test tube, amount of milk poured into each test tube, amount of renin mixed inside test tube, same weather condition, same temperature of the milk inside the test tube.

* To reduce threats to internal validity I cannot be biased toward one design more than another. I did not choose a paper airplane that I had seen before. I chose three paper airplane models at random so I wouldn’t have a chance to think one was better than the other. I also do not want to change anything

This experiment shall be repeated twice or more to enhance accuracy of the results obtained. Besides detecting systematic errors, this experiment would aid on the technique and understandings to the correct use of these equipments.

The Absolute approach calls for the trial design and DTS to achieve the same results, in whichever method preferred, as pre-determined by the acceptance criteria.

Quantitative research design is an excellent way of finalizing results and proving or disproving a hypothesis. The structure has not changed for centuries, so is standard across many scientific fields and disciplines. After statistical analysis of the results, a comprehensive answer is reached, and the results can be legitimately discussed and published. Quantitative experiments
