- State and explain the significance of the three basic principles of experimental design.arrow_forwardThe Reading Company (TRC) develops educational products that it tries to sell to school districts all across the United States. TRC prides itself on only marketing products that have been empirically supported by research. It has developed a new product that is designed to improve the reading comprehension ability of 3rd through 6th graders. The product costs US$20,000 a year. Obviously, it will be easier to sell this product if TRC can provide potential buyers with empirical evidence that the product actually works. Their researchers took a random sample of 18 students from a school district that had a mean reading comprehension score of µ = 400 with a standard deviation of 100. The population of reading comprehension scores is normally shaped. After using the product for two semesters the mean reading comprehension scores for these 18 students was M = 443, z = 1.82, d = .43. Based on the obtained z value for the above TRC study and an ⍺ level of .05, do they have sufficient evidence…arrow_forwardThe Reading Company (TRC) develops educational products that it tries to sell to school districts all across the United States.

- What are the pros and cons of refining your research question before your literature review compared with after your literature review?arrow_forwardVitamin E and the Risk of Prostate Cancer: Klien et al (2011) conducted the following study to determine the effect of vitamin E and selenium treatment on the risk of developing prostate cancer in healthy men. A total of 34,887 men from different study sites in the United States, Canada, and Puerto Rico were randomly selected. To be eligible to participate, the men had to take a rectal examination that showed he was not suspicious of having prostate cancer and be aged 50 years or older for black men and 55 years or older for all others. Each man was randomly assigned to receive one of four treatments: selenium, vitamin E, selenium and vitamin E together, or a placebo. The men were followed up after 8 years to see if they had developed prostate cancer or not. The main question of interest is to determine if the risk of developing prostate cancer differs by the treatment taken. The data are summarized in the table below: No Prostate Cancer Prostate Cancer Total Selenium 8,752 8,737 8,702…arrow_forwardOutline the components of the classical experimental design.

The price of gasoline and diesel changes daily, however, your customers expect to be quoted a price for delivery services days, weeks, and sometimes, MONTHS in advance. Therefore, your firm relies heavily on forecasting the price of fuel. Which method of forecasting might you use, qualitative or quantitative? And finally, what are the limitations to business forecasting.arrow_forwardSummarize the advantages and disadvantages of qualitative research when compared to experimental or survey research? Under what circumstances would a researcher choose a qualitative design?arrow_forward
- You are recently promoted as the chief traffic management officer of a major city in the country. Based on recent data, you learned that one of the leading causes of road accidents is over speeding. In your desire to minimize road accidents, you went out to observe how traffic management rules are implemented on the streets. Your attention was caught by a fast - moving car that seemed to be breaking the speed limit of 100 kilometers per hour(km/hr.), and so you followed it along the highway. After a short time, the driver of the car noticed you and started to slow down. Eventually, he stopped on the side of the road. Supposed the speed of the car had been noted during this time and is modeled by the quadratic equation y = 3x² + 17x - 20, where y represents the speed of the car in km/hr. and x represents the number of minutes after you started following the car. How long did it take for the car to be under surveillance before it could finally stop on the side of…arrow_forwardPlease help me understand the concept of hypothesis testing and all the important factors that should be understood in order to be able to accurately answer questions of this nature. I find myself confused when looking at some of the factors that should be considered before answering these questions and more confused when performing the steps. Please guide me in your way and thank you in advance. Individuals involved in the criminal justice system are thought to display many dynamic criminogenic needs, meaning that they have areas of need that are specifically associated with higher risk of offending (e.g., substance use, antisocial peers etc…). Research has demonstrated that addressing these needs in treatment can lead to reductions in committing new crimes when released from prison. A researcher thinks that offenders may also have some strengths that, if built upon, can also lead to further reductions in recidivism. The researcher has 10 incarcerated offenders take 2 assessments:…arrow_forwardSuppose you work for a leading software house of Pakistan as an HR Manager. Your company has been facing a high turnover rate of employees in the recent months. 20 employees out of the 50 member staff has left the company in the past two months. The high turnover rate is negatively impacting the performance of the company. Your CEO is concerned about this issue and he has asked you to conduct a research study to find out the causes of the high turnover rate in your company. You believe qualitative research to be the suitable type of research for this study. Plan a qualitative study to investigate high turnover rate in your company by answering the following questions: Q. What research paradigm would you choose to conduct this study? Justify your choice.
