Find the rise and run between each set of points.

Well, I can’t see the points, but to find the rise and run:

Start at the lowest of the 2 points and count directly up, one unit at a time and that’s your rise. Then, once your on the level of the other point, count horizontally in that direction until you get there and that’s your run. After, put it in fraction form with rise on top of run.

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

there are a number of factors that should be analyzed before starting an observational study.

the main four factors are:

i) introduction:   this should be analysed to check whether the purpose of the study is correctly established and the data recorded are appropriate for the study

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.
