Question

Read each example of data below and identify whether it is qualitative or quantitative. 28.5 cm tall rough-textured the bird bobbed its head up and down.

Answer 1

A general rule of thumb is that if numbers are involved it's quantitative and if characteristics are involved its qualitative, so in this case it'd be quantitative.

Answer 2

1. 28.5 cm tall: qQuantitative data.
2. Rough-textured: Qualitative data.

Explanation:

Quantitative data include measure of value that are expressed in numbers. For example, 365 days in a year, 24 hours in a day, 7 continents of the world etc.

Qualitative data is non-numerical data. This includes characteristics (color, texture and taste), symbols and description. Its subjective and cannot be measured.

The statement in the question has both qualitative and quantitative data.

1. 28.5 cm tall: This is a quantitative data. It is expressed in form of numbers.
2. Rough-textured: This is qualitative. It defines one of the characteristics of the bird.

An easy way to differentiate between the two is to find whether the data is expressed in numbers. If numerical are involved e.g. mass of 78 pounds, 250 ml of water, force of 10N etc., then the data is quantitative. If it can’t be counted or measured, then its qualitative.
