Jason and beth are married and don’t have any kids yet. they are out of debt except for their house, and they have a full emergency fund. but beth’s car has sputtered its last breath. fortunately, she’s found a new one for hundreds less than invoice. the payments will be less than a fourth of their combined take- home pay. this fits dave’s formula, and the payments can be squeezed into their budget. she’ll take $2,000 out of their emergency fund for the down payment. jason thinks it’s a really bad idea. why?

Pay cash for the whole car.

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.
