Abstract
In this essay reader will be able to understand qualitative data
by chosen gender or position and quantitative data by chosen
either intrinsic or extrinsic. Also the explanation of data that
was selected and examining sets of data that was learned will
also be explained. Microsoft excels with data use of mean
median mode measures and two measurement of variability
standard deviation and variance will be analysis for reader to
understand. In conclusion you will be able to know if the
measurement is applicable and chart and graph of each results
and why they are important in conveying information in a visual
format and standard deviation and variation are important and a
discussion of what was learned from the results in process.
Introduction
Most prominent studies in companies are job satisfaction, which

7. refers to a person’s contentment with his or her job. There are
some factors that can contribute to a person satisfaction in
workplace like environment, employee relations, salary, or even
work load. Satisfaction of a job is measured by the use of
rating scales where employees described their feedbacks to their
on the job environment. Over time theories have evolved the
perceived connections between job satisfaction and other
variable such as workplace productivity.
Chosen Variables
Job satisfaction is all about an employees serving that the work
is done completely and i=well with minimum or no errors. In
order to have a well entitled job satisfaction, there are a number
of factors to consider in job satisfaction. One of the reasons is
the personality of the employees and also the way the company
treats its employees. In the field of data satisfaction I will look
at gender and intrinsic.
Difference in variable types
Qualitative is non numerical measurement on set of objects and
people and quantitative is numerical measurement for set of
objects or people. The main aspect for the selection of the two
was to examine the reaction of the employees according to age
on the job satisfaction. The both on the positive and the
negative feedback on the data obtained. In the intrinsic area, the
survey was carried to help in also obtaining the employee job
satisfaction positive feedback on it.

Explanation of descriptive statistics
On the part of age, there are many who responded on the
data collection. More of them were clarifying that the data set
was only meant to be a way for a company to archive. Many
proved to be closely supervised in order to perform their duties.

8. Those of ages from 45 and above proved to be giving
satisfactory jobs since they have already been able to master
their duties and also they are aware of it very well. There are
also skilled and experts since their working experience in their
occupation have been taken for a long time.
Calculations on the mean, mode, median, variance and standard
deviation for both gender and intrinsic

Graph of the data set
Conclusion quantitative and qualitative research are two
approaches to gathering data and they can be used together and
two approaches get into similar methodology at time they look
for different types of information . Each has advantages and
disadvantages but what works best depends on what a person is
studying and hoe much information and detail you need.
