Answer 1

The following different measurement systems are classified as:

1. nominal scale
2. ratio scale
3. ordinal scale
4. ordinal scale
5. ratio scale
6. ordinal scale
7. ordinal scale
8. nominal scale
9. ordinal scale
10. nominal scale
11. ratio scale
12. ratio scale

Step-by-step explanation:

The question involves identifying the levels of measurement for different types of data.

The four levels are nominal, ordinal, interval, and ratio.

1. Your checking account number is a nominal scale because it is a label that serves as an identifier, with no quantitative value.
2. Your checking account balance is measured on a ratio scale because it has a true zero point and the differences and ratios between balances are meaningful.
3. Your score on the first statistics test is an example of ordinal scale if it's a letter grade (A, B, C, etc.) and a ratio scale if it's a numerical percentage, as it can be ordered and has a true zero value.
4. A response to an attitudinal statement with a numerical scale from 1 to 5 is an ordinal scale because the numbers represent an order of agreement but the intervals between them are not necessarily equal.
5. Time for swimmers to complete a race is a ratio scale because it has a true zero point and differences and ratios between times are meaningful.
6. Months of the year are an example of an ordinal scale, assuming they are ordered, but they do not have a true zero point or equidistant intervals.
7. Socioeconomic status classified as low, middle, and upper classes is ordinal scale because the categories can be ordered but the intervals are not necessarily equal.
8. Blood type of individuals is nominal scale because it represents categories without any order or numerical difference.
9. Pollen counts on a scale of 1 to 10 represent an ordinal scale because they indicate a level of severity, not an exact count or measurable quantity.
10. Region numbers of Ethiopia might be nominal scale if they are just used as labels, or ordinal if there's an implied order.
11. The number of students in a college is a ratio scale because it has a true zero, and differences and ratios make sense.
12. The net wages of a group of workers are on a ratio scale because they have a true zero point, and you can perform meaningful arithmetic operations on the data.
