Data Analysis of Career Majors

This assignment focuses on analyzing data related to career choices (accounting, HR, and marketing). Students classify variables as qualitative or quantitative, construct frequency tables and charts for categorical variables, and calculate numeric summaries for continuous variables. The assignment also involves answering specific questions about starting salaries, experience levels, and potential correlations between majors and earnings. Finally, students summarize their findings and discuss the limitations of the dataset.

PART 1
a. The set of qualitative variables and quantitative variables from the given data variables are
shown below:
Qualitative variables (variables which are having non- numeric set of data)
 Major
 Education background
Quantitative variables (variables which are having numeric set of data)
 Starting Salary (per year)
 Previous Experience (in years)
Major has a non-numeric data and hence, it is a qualitative variable.
Education background has a non-numeric data and hence, it is a qualitative variable.
Starting Salary (per year) has a numeric data and hence, it is a quantitative variable. Moreover,
it is noteworthy that salary data does not have any decimal and therefore, the data would be
classified as discrete.
Previous Experience (in years) has a numeric data and hence, it is a quantitative variable.
Moreover, it is noteworthy that salary data have decimals and therefore, the data would be
classified as continuous.
b. Frequency tables for qualitative variables

years) is highlighted below:

e. The responses for the questions are shown below:
S. No. Question Answer
(i) The average/mean annual starting salary of accounting
major employee
¿ ∑ of annual starting salary
totalemployee∈accouting major
¿ $ 681000
10 =$ 68,100
(ii) The median annual starting salary of marketing major
employee
$69,000.
(iii) The average number of years of the job for an HR major
employee
¿ Total number of years of job∈ HR major
total employee∈ HR major
¿ 22.5
10 =2.25 years
(iv) Considering the average starting salaries of the various majors, it does not seem that
there is any significant correlation between the starting salaries and the majors.
Further, part of the difference in salaries may be attributed to difference in educational
background along with the experience.
(v) Summarization of information provides an overview of the information which is
helpful in exploring the existing cross linkages which otherwise may be missed if the
data is looked at in an individual manner. Further, the identification of these cross
linkages is considered to be extremely fruitful in enhancing the overall creativity and
improves decision making.

PART 2
Summary
The aim of this report is to outline the career prospects in relation to the chosen three major
fields i.e. accounting, HR and marketing. This would be proving useful for students who can use
the findings of the report to make career selections in a more prudent manner so as to have a
better career going forward. The requisite information for this is obtained from 30 members of
staff and this captures various variables such as starting salary, experience and education
background.
The given data suggests that a majority of respondents have earned a college degree while MBA
also seems to be popular considering sizable representation. Further, the respondent which has a
higher degree also receives higher starting salary as MBA holders receive the maximum
beginning salary and diploma holders receive the minimum salary. The average starting salary on
an annual basis for the given majors tend to range in the interval $ 68,000 - $ 75,000. But the
critical factor of salary seems to be the underlying education background rather than the major
field. However, in terms of major marketing seems to have a slight edge which may not represent
any significant deviation from other majors.
But the conclusions drawn from this study should be taken with caution owing to the sample
being very limited in size and hence for greater insights into the various aspects a larger data set
may be recommended. However, within the limited purview of the given data there seems to be
evidence of education background emerging as a critical parameter for determining the starting
salary unlike the majors which does not seem critical.
