An Introduction to Business Statistics
1.1 Quantitative/Interval. The differences between average monthly temperatures are
meaningful, but there is no true zero point, i.e., absence of temperature.
1.2 Quantitative/Ratio. The differences between average monthly rainfalls are meaningful, and
there is a true zero point, because there may be a month without any rainfalls.
1.3 Qualitative/Ordinal. You can rank education level, but the differences between different
M
educational levels cannot be measured.
ED
1.4 Qualitative/Nominal. The marital status is just a label without a meaningful difference, or
ranking.
1.5 Quantitative/Ratio. The differences between ages of respondents are meaningful and there
C
is a true zero point: an age of the respondents that equals zero represents the absence of age.
O
1.6 Qualitative/Nominal. The genders are merely labels with no ranking or meaningful
N
difference.
N
1.7 Quantitative/Interval. The differences between birth years are meaningful, but there is no true
zero point with calendar years.
O
1.8 Qualitative/ Nominal. The political affiliations are merely labels with no ranking or
IS
meaningful difference.
SE
1.9 Qualitative/ Nominal. The races of the respondents are merely labels with no ranking or
meaningful difference.
U
1.10 Qualitative/ Ordinal. You can rank the performance rating, but the differences between
different performance ratings cannot be measured.
R
1.11 Qualitative/ Nominal. The uniform numbers of each member of the school’s sport team are
labels with no ranking or meaningful difference.
1.12 Qualitative/ordinal. The differences in the data values between class ranks are not
meaningful.

1.13 Quantitative/Ratio. The differences between final exam scores for your statistics class
are meaningful, and there is a true zero point because a student who did not take the exam
would have a score of zero.
1.14 Qualitative/Nominal. The state in which the respondents in a survey reside is a label and it
is meaningless to talk about the rating of this value.
1.15 Quantitative/Interval. The differences between SAT scores for graduating high school
students are meaningful, but there is no true zero point because a student with an SAT score
M
equal to zero does not indicate the absence of a score.
ED
1.16 Qualitative/Ordinal. You can rank movie ratings, but the differences between
different ratings cannot be measured.
C
1.17 Qualitative/ordinal. The differences in the data values between ratings are not meaningful.
O
1.18 Qualitative/ordinal. The differences in the data values between ratings are not meaningful.
N
1.19 Cross-sectional
N
1.20 Time series
O
1.21 Time series: Men weekly earnings over the five years.
IS
Time series: Women weekly earnings over the five years.
1.22 Cross-sectional data: Men and women workers weekly earnings for any one particular year.
SE
1.23 Cross-sectional: The number of 8x10, 11x14 and 13x19 prints sold over a particular year.
U
1.24 Time series: the number of 8x10 prints sold over the four years.
Time series: the number of 11x14 prints sold over the four years.
R
Time series: the number of 13x19 prints sold over the four years.
1.25 Descriptive statistics, because it identifies a sample mean.
1.26 Inferential statistics, because the statements about comparing the average costs of a hotel
room in two states was based on results from samples taken from two populations.
