Task 01: An Example of a Descriptive Analysis

Task

Data set: Data_01.sav (On Ilias: … » Lectures » Lecture 01 Introduction » Data Resources)

Description: "Data_01.xls"

This file contains a partial sample from a marketing survey. Ca

y out an analysis of the data. Are there

any outliers? Are there any other unusual features?

Hints: Please note the meaning of the variables. The variables are described in "Data 01 Example.xls".

Use key figures, frequencies and histograms.

Descriptive Analysis

Note: Mean, median, standard deviation, skewness and kurtosis are not very meaningful as far as gender is

concerned, while Missing, Minimum etc. are useful.

Sample size N = 198. No missing values. Mean and median are different: some distributions seem to be

skewed to the left or right. Perhaps there are some outliers. Certain minimum and maximum values

suggest this.

Hint: Copy the entire required syntax to the beginning of your solution.

See "How to copy SPSS output..." in the appendix to this document.

Hint: Copy the relevant parts of the output into your solution as pictures.

There is an inco

ect category "3" while according to the information

provided there should only be "1" (male) and "2" (female).

The number of men and women is about equal.

Maximum age = 82 is not impossible. There is a peak at 20 to 25 years.

This may indicate a sampling problem. Was a disproportionate number

of young people included?

This distribution is right-skewed (skewness = .701; mean (37.93) >

median XXXXXXXXXXThe kurtosis XXXXXXXXXXdoes not differ meaningfully

from 0.

The value 0 could be a typo because 0 is not an element of the scale.

This distribution is right-skewed (skewness = .135; mean (3.48) >

median XXXXXXXXXXThe kurtosis XXXXXXXXXXindicates a slightly flat

distribution.

This distribution is left-skewed (skewness = -.064; mean (3.80) <

median XXXXXXXXXXThe kurtosis XXXXXXXXXXindicates a slightly flat

distribution.

This distribution is right-skewed (skewness = .360; mean (3.05) >

median XXXXXXXXXXThe kurtosis XXXXXXXXXXdoes not differ appreciably from 0.

The value 7 is chosen rarely or not at all for all three items even though

the value 6 is often chosen for attitude1 and attitude2. How is the

wording of the items and possible responses?

Is the 7th response option too extreme?

educ is left-skewed (skewness = -1.095; mean (5.44) < median (6.00)).

This may indicate a sampling problem. Education is more or less

normally distributed within the population. Why is the distribution

distorted? Is this a sample of individuals who have gone through higher

education?

Assignment 01_EN_2018 First Steps with SPSS, p. 3

The minimum income is 25.3 and seems very far removed from the

est of the sample. Although this kind of income is possible (e.g. part-

time work), this value could also be false. Is it an input e

or?

This distribution is also right-skewed (skewness = .493; mean

XXXXXXXXXX) > median XXXXXXXXXXFurthermore, the kurtosis (1.956)

indicates a peaked distribution.

Conclusion

This seems to be a sample of adults in which young adults are represented disproportionately. The sample

also seems to be highly educated.

On average, women seem to have a lower

income. However, the boxplot shows that the

difference is probably not significant.

Hint: Sometimes there is a red "information" icon in the suggested solution. In this case, you will

find additional analytical steps or further information next to the same icon in the section

"Additional Information".

Hint: Position the conclusion at the end of your

solution under the heading "Conclusion".
