A nutritionist seeks to conduct a clinical trial on the effects of eating papaya on cholesterol levels in the blood. The targeted parameter is mean cholesterol with a margin of error of no more than 0.01 mg/dL. What might be a question the nutritionist wants to consider? A. What is the 5th percentile of people by weight in this study? B. What is the maximum margin of error I should consider? C. Can I take a mean with continuous quantitative data? D. What is the minimum number of people I need for the study?
Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.
