Verified step by step guidance

1. Understand the different levels of measurement: nominal, ordinal, interval, and ratio. Ordinal data represent categories with a meaningful order but without consistent intervals between categories.
2. Review each option to determine its level of measurement:
3. 1. Student ID numbers are nominal data because they are labels without any inherent order.
4. 2. Number of cars sold is ratio data because it is a count with a true zero and meaningful intervals.
5. 3. Customer satisfaction ratings are ordinal data because they have a clear order (from very dissatisfied to very satisfied) but the differences between categories are not necessarily equal.
6. 4. Temperature in degrees Celsius is interval data because it has ordered values with equal intervals but no true zero point.
