A study conducted by researchers was designed "to determine if application of duct tape is as effective as cryotherapy (liquid nitrogen applied to the wart for 10 seconds every 2 to 3 weeks) in the treatment of common warts."The researchers randomly divided 51 patients into two groups. The 26 patients in group 1 had their warts treated by applying duct tape to the wart for 6.5 days and then removing the tape for 12 hours, at which point the cycle was repeated for a maximum of 2 months. The 25 patients in group 2 had their warts treated by cryotherapy for a maximum of six treatments. Once the treatments were complete, it was determined that \(85 \%\) of the patients in group 1 and \(60 \%\) of the patients in group 2 had complete resolution of their warts. The researchers concluded that duct tape is significantly more effective in treating warts than cryotherapy. (a) What is the research objective? (b) What is the population being studied? What is the sample? (c) What are the descriptive statistics? (d) What are the conclusions of the study?

Short Answer

Expert verified
The objective is to compare duct tape and cryotherapy for wart treatment. The population is patients with warts; the sample is 51 patients. The statistics show 85% effectiveness for duct tape and 60% for cryotherapy. The conclusion is that duct tape is more effective.

Step by step solution

01

- Identify the research objective

The research objective is to determine if the application of duct tape is as effective as cryotherapy in the treatment of common warts.
02

- Identify the population and sample

The population being studied consists of patients who have common warts. The sample comprises the 51 patients enrolled in the study, with 26 patients in group 1 and 25 patients in group 2.
03

- Determine the descriptive statistics

The descriptive statistics provided are the percentages of patients in each group whose warts completely resolved after treatment: 85% in group 1 (duct tape) and 60% in group 2 (cryotherapy).
04

- State the conclusion of the study

The researchers concluded that duct tape is significantly more effective in treating warts than cryotherapy, based on the higher success rate in group 1 compared to group 2.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

research objective
In any study, the research objective serves as the foundation for your investigation. It tells us what you are trying to discover or prove. To illustrate, let's consider the given study on wart treatments. Here, the main objective is to find out if duct tape is as effective as cryotherapy in the treatment of common warts. The researchers want to compare these two methods to see which one works better. This clear goal drives the design, implementation, and analysis of the study. In short, knowing the research objective helps you understand why the study is being conducted and what it aims to achieve.
population vs. sample
Understanding the difference between a population and a sample is crucial in statistical analysis. Here, the 'population' refers to everyone who has common warts. However, studying every single person with warts would be impractical. That's where a 'sample' comes in. A sample is a smaller group chosen from the population that is intended to represent the population. In this study, the sample consists of 51 patients with common warts. These patients are split into two groups: 26 patients using duct tape (group 1) and 25 patients using cryotherapy (group 2). By studying this sample, researchers can make inferences about the broader population of people with common warts.
descriptive statistics
Descriptive statistics summarize and describe the features of a dataset. They help convert data into understandable information. In this study, the descriptive statistics are the percentages of successful treatments: 85% for the duct tape group and 60% for the cryotherapy group. These percentages quickly inform us about the effectiveness of each treatment. By looking at these numbers, you can immediately see that a higher proportion of patients in the duct tape group had a complete resolution of their warts compared to the cryotherapy group. Descriptive statistics make it easy to compare and understand the essential findings of your study.
conclusion of the study
The study's conclusion wraps up the findings and their significance. In this case, the conclusion is that duct tape is significantly more effective in treating common warts than cryotherapy, based on the provided data. The 85% success rate with duct tape against the 60% success rate with cryotherapy led the researchers to this conclusion. It's important to note that conclusions should always be backed by data and clearly relate to the original research objective. Here, the researchers could state their findings with confidence because the data supported the claim, giving a clear and strong conclusion to their study.

You wonder whether green tea lowers cholesterol. (a) To research the claim that green tea lowers LDL (so-called bad) cholesterol, you ask a random sample of individuals to divulge whether they are regular green tea users or not. You also obtain their LDL cholesterol levels. Finally, you compare the LDL cholesterol levels of the green tea drinkers to those of the non-green tea drinkers. Explain why this is an observational study. (b) Name some lurking variables that might exist in the study (c) Suppose, instead of surveying individuals regarding their tea-drinking habits, you decide to conduct a designed experiment. You identify 120 volunteers to participate in the study and decided on three levels of the treatment: a placebo, one cup of green tea daily, two cups of green tea daily. The experiment is to run for one year. The response variable will be the change in LDL cholesterol for each subject from the beginning of the study to the end. What type of experimental design is this? (d) Explain how you would use blinding in this experiment. (e) What is the factor? Is it qualitative or quantitative? (f) What factors might you attempt to control in this experiment. (g) Explain how to use randomization in this experiment. How does randomization neutralize those variables that are not controlled? (h) Suppose you assigned 40 subjects to each of the three treatment groups. In addition, you decided to control the variable exercise by having each subject perform 150 minutes of cardiovascular exercise each week by walking on a treadmill. However, the 40 subjects in the placebo group decided they did not want to walk on the treadmill and skipped the weekly exercise. Explain how exercise is now a confounding variable.

In Problems 11-22, identify the type of sampling used. 24 Hour Fitness wants to administer a satisfaction survey to its current members. Using its membership roster, the club randomly selects 40 club members and asks them about their level of satisfaction with the club.

A pharmaceutical company has developed an experimental drug meant to relieve symptoms associated with the common cold. The company identifies 300 adult males 25 to 29 years old who have a common cold and randomly divides them into two groups. Group 1 is given the experimental drug, while group 2 is given a placebo. After 1 week of treatment, the proportion that still have cold symptoms in each group are compared. (a) What is the response variable in this experiment? (b) Think of some of the factors in the study. How are they controlled? (c) What are the treatments? How many treatments are there? (d) How are the factors that are not controlled dealt with? (e) What type of experimental design is this? (f) Identify the subjects. (g) Draw a diagram similar to Figure \(7,8,\) or 10 to illustrate the design.

In Problems 11-22, identify the type of sampling used. To estimate the percentage of defects in a recent manufacturing batch, a quality-control manager at Intel selects every 8 th chip that comes off the assembly line starting with the 3rd until she obtains a sample of 140 chips.

The General Social Survey asked, "About how often did you have sex in the past 12 months?" About \(47 \%\) of respondents indicated they had sex at least once a week. In an internet survey for a marriage and family wellness center, respondents were asked, "How often do you and your partner have sex (on average)?" About \(31 \%\) of respondents indicated they had sex with their partner at least once a week. Explain how the delivery method for such a question could result in biased responses.
