An observational study is retrospective if it considers only existing data. It is prospective if the study design calls for data to be collected as time goes on. Tell which of the following observational studies are retrospective and which are prospective. A sample of moose in a national park are given ear tags so that naturalists can track their growth, movement, and physical condition during a ten-year study.

Retrospective: data are collected from the past by going back in time Prospective: data are collected in the future
The sample of moose are given ear tags stich that they can gather data on their growth, movement, and physical condition in the future.
This then implies that the data are collected in the future and thus the observational study is prospective.

1. Which of the following statements is incorrect?
The median is the most appropriate measure of central tendency for highly-skewed data distributions.
The variance is always greater than the standard deviation.
A 10% trimmed mean of a given data is solved by removing the largest 10% and smallest 10% of the data, then computing for the mean.
The coefficient of variation is the ratio between the mean and the standard deviation.

What is the meaning of percentile?
I am confused by the term percentile. Once my teacher told me that percentile means the percentage with respect to the score of the highest achiever.
This means that if in a competition I got 80 out of 100 and the highest score in that competition was 90 out of 100 then my percentile would be 80 90 100 = 88.89
So I got 80 % and 88.89 percentile.
I was believing that my above concept was right.
But when I see the definition of percentile on Wikipedia then I got something new (but I don't understand this definition) and then I thought that what my teacher told me was wrong.
Kindly tell me if my teacher right or wrong.
