Which of the following are characteristics of ratio level data?

1.Unequal spacing

2.Negative scores

3.Equal spacing

4.Increasing or decreasing order

5.Absolute zero point

A1, 2 & 3 only

B2, 3 & 4 only

C3, 4 & 5 only ✓ Correct

D1, 2 & 5 only

Correct answer: (C) 3, 4 & 5 only

Explanation

Ratio-level data have equal spacing, an increasing or decreasing order, and an absolute zero point.

Equal intervals mean the differences between values are consistent and meaningful.

A true zero indicates the complete absence of the quantity measured.

Order lets the values be ranked from low to high.

Unequal spacing is not a feature, since ratio intervals are equal.

Negative scores cannot occur because zero is the fixed lower bound.
