Question

the lengths (in centimeters) of 22 ford automobiles are listed. identify the level of measurement of the data set. explain your reasoning. 403.9 407.2 409.6 416.2 420.8 437.7 439.9 442.6 460.7 466.6 470.9 478.2 480.2 482.9 482.9 485.2 486.9 486.5 497.3 504.6 534.3 535.7 what is the data sets level of measurement? explain your reasoning. a. ratio. the data can be ordered and differences between data entries are meaningful, and the zero entry is an inherent zero. b. nominal. the data are categorized using numbers, but no mathematical computations can be made. c. interval. the data can be ordered and differences between data entries are meaningful, but the zero entry is not an inherent zero. d. ordinal. the data can be arranged in order, or ranked, but differences between data entries are not meaningful.

Explanation:

Length is a quantitative variable. The data can be ordered (smaller to larger lengths), differences between lengths are meaningful (e.g., the difference between two car lengths), and a length of 0 cm means the complete absence of length (inherent zero). Ratio - level data has these characteristics.

Answer:

A. Ratio. The data can be ordered and differences between data entries are meaningful, and the zero entry is an inherent zero.
