Question 1
1. Gender
Data type: Categorical
Measurement level: Nominal
This is because gender type male and female is measured at nominal scale.
2. Approximate undergraduate college GPA
Data type: Continuous
Measurement level: Ratio
This is because undergraduate college GPA such as 1.0 to 4.0 would be a mathematical operation
and hence, ratio is the measurement level.
3. Number of hours per week
Data type: Continuous
Measurement level: Ratio
This is because number of hours per week would be a mathematical operation and hence, ratio is
the measurement level.
4. Ideal number of children for a married couple

This is because number of children would be a mathematical operation and hence, ratio is the
measurement level.
5. Describe parents
Data type: Categorical
Measurement level: Ordinal
This is because the given statistics shows the order 1 for the respective month which dominate up
to order 5 for father and hence, the ordinal is the measurement level.
Question 2
Given data
(a) Computation of mean, median and mode
These values have been computed with the help of excel functions i.e.
Mean = AVERAGE ()
Median = MEDIAN ()

Mode = MODE ()
(b) It can be seen that measures of central tendency i.e. mean, median and mode are not
equal and hence, the measure of central tendency is not agreed.
Mean ≠ Median≠ Mode
(c) Standard deviation
This has been computed with the help of excel functions STDEV ().
(d) Sort and standardized the data
x=724.67
s=114.28
For each of the given value, it is essential to find the standardized score as highlighted below:
zi= ( xi−x
s )
