IN your answer include this>
- the treatment give to the expertimental group
- treatment to be give to the control group
- data collected
-when
How do i do this question
this is sooooo unhelpful. the least you could do is actually give an answer.
nothing
To investigate the claim made in the television advertisement that a certain brand of cough drop reduces coughing for 8 hours, you can conduct a randomized controlled trial. Here's an outline of the investigation:
1. Participants: Recruit a group of individuals who frequently experience coughing. Ensure that the sample size is sufficient for statistical analysis.
2. Experimental Group: Assign half of the participants to the experimental group. Provide them with the specific brand of cough drops being advertised and instruct them to use it as directed whenever they experience coughing.
3. Control Group: Assign the other half of the participants to the control group. Do not provide them with any cough drops or provide them with a placebo such as sugar pills, which do not have any active cough-suppressing ingredients.
4. Data Collection: Use a standardized method to collect data on coughing frequency and severity. You could provide participants with a cough diary, where they record the number of coughing episodes and rate the intensity of their cough on a numerical scale at regular intervals throughout the day.
5. Duration: Conduct the study over an appropriate period to evaluate the claim. In this case, since the claim is about reducing coughing for 8 hours, you might consider conducting the study over multiple days or weeks to capture variations in participants' cough patterns.
6. Comparison and Analysis: Compare the data collected from the experimental group (using the specific brand of cough drops) with the control group (using a placebo or no treatment). Analyze the differences in cough frequency and severity between the two groups to determine if the cough drops indeed reduce coughing for 8 hours.
7. Statistical Analysis: Use appropriate statistical methods to analyze the data, such as t-tests or chi-square tests, to assess if any observed differences are statistically significant.
By conducting this investigation using a randomized controlled trial design, you can effectively evaluate the validity of the claim made in the television advertisement about the cough drop's effectiveness in reducing coughing for 8 hours.
