Using the following stem & leaf plot, find the five number summary for the data by hand. 1|5 6 2|3 7 9 3|3 7 4|4 6 8 9 5|0 3 4 5 8 6|2 3

a. min =
b. q1 =
c. med =
d. q3 =
e. max =

Step-by-step explanation:

given is a set of data in steam and leaf plot.

Before finding five number summary, let us write in full form from stem and leaf

The data set consists of

15, 16, 23, 27, 29, 33, 37, 44, 46, 48, 49, 50, 53, 54, 55, 58, 62,63

The data itself is an ascending order.  Hence we find min as I entry max as last entry median as the average of 46 and 48, since there are 18 entries.

Q1 is the 5th entry and Q3 is the 5th entry from the last.

We find that

a) Minimum: 15

b) Quartile Q1: 29

c) Median: 47

d) Quartile Q3: 54

e) Maximum: 63

answer: the answer is 23

step-by-step explanation:

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.
