Question- follow the steps below. once completed answer the questions that follow.
1. use a straight edge to draw the line segment ab.
2. place the compass on one end of the line segment.
3. set the compass length to any length longer than halfway down the line.
4. without changing the compass width, draw an arc on each side of the line.
5. again without changing the compass width, place the compass point on the other end of the line. draw an arc on each side of the line so that the arcs cross the first two.
6. using a straightedge, draw a line between the points where the arcs intersect.
where the line crosses segment ab is the midpoint of the line, and the line is perpendicular to the segment ab, so our new line is the perpendicular bisector of ab. use your protractor and ruler to check your work. did it work? if you follow these steps, will you ever get a line that is not the perpendicular bisector? explain.

introduction, methodology, results, discussion

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.

answer: howdy
