Expert verified

Ratio data

Step by step solution

01

Given information

The weights of newborn babies are recorded in grams.

02

Differentiate between the four scales of measurement

Nominal: Data that can only be categorized and cannot be ranked

Ordinal: Data that can be categorized and ordered

Interval: Data that be categorized, ordered, and have well-defined gaps

Ratio: Data that be categorized, ordered, has well-defined gaps, and meaningful interpretation of zero

03

Identify the data based on the scale of measurement

The following can apply to the weights of newborns:

  • They can be categorized into different ranges.
  • They can be ordered in increasing or decreasing order.
  • The difference between any two values can be meaningful.
  • The value zero grams can be meaningful or being the base level.

Thus, the weights of newborns are measured on a ratio scale of measurement.
