- 4. What is the purpose of randomization in an experiment? How would this be achieved in non-experimental studies?
Homework Answers
Answer: The major purpose of the randomization in an experiment is to reduce the mistakes or the bias responses in the research.
This can be achieved in the ni - experimental studies by indulging other methods of the studies such as cohort studies, multivariable studies etc. This can be obtained without the indulgence of the randomization in the non experimental studies.

Randomization can occur at two points in an experimental study. Design your own study, specifying whether your selection of subjects is randomized or non-randomized. Also note whether the assignment to treatment and control groups is randomized or non-randomized. What are the main characteristics of your experiment that make it either randomized or non-randomized? Be sure your example is for experimental research and not a survey, case study, or correlational design.

Solve 1.Define reactivity as it relates to a scientific experiment. Provide two specific examples of how reactivity might affect a naturalistic observation experiment. 2.Explain the difference between a non-experimental method and an experimental method. Include a description of how each method is performed and identify which type of validity is more associated with each one. 3.Define both qualitative data and quantitative data. Then, identify the purpose, the group who is studied, and the role of the researcher for each type...

There is always frequent conflate with the term “laboratory study” with a randomized experiment and “field study” with non-experimental research – do you think this is always true? What are some examples of field studies that can sometimes be more impressive than laboratory studies?

3-3. Randomization. A randomized clinical trial was designed to compare two different treatment approaches for irritable-bowel syndrome. The purpose of randomization in this study was to: a. increase patient compliance with treatment. b. obtain comparison groups that are similar on other variables that may influence the disease. c. obtain comparison groups that are similar on any other variables measured in the study. d. Increase the likelihood of finding a significant effect of treatment. e. obtain a representative sample in the...

Titration lab State the purpose of this experiment. Describe the function of the phenolphthalein in this experiment. How would this experiment be different if you had forgotten to add the phenolphthalein State evidence from the lab that the endpoint was reached. It takes 75ml of a 2.5M HCl solution to neutralize 55ml of a base of unknown concentration. Calculate the concentration of an unknown basic solution. If the actual concentration of the HCl was 0.33M what is your percent error?...
