Chapter 1, Problem 49A

Solution

(a)

Interpretation: Whether the given data is qualitative or quantitative needs to be determined.

Concept Introduction: Quantitative data are measures of values or counts and are expressed as numbers. It is the data about numeric variables. Qualitative data are measures of 'types' and may be represented by a name, symbol, or number code.

The given represents data of “Types of Apples Grown in Bioscience Greenhouse”, which contains numeric values, shown below:

Types of Apples Grown in Bioscience Greenhouse
Delicious	$47\%$
Macintosh	$26\%$
Fuji	$12\%$
Granny Smith	$10\%$
Others	$5\%$

As it can be seen from the figure that data is expressed in numbers, thus, the figure represents the quantitative data.

(b)

Interpretation: Whether the given data is qualitative or quantitative needs to be determined.

Concept Introduction: Quantitative data are measures of values or counts and are expressed as numbers. It is the data about numeric variables. Qualitative data are measures of 'types' and may be represented by a name, symbol, or number code.

The figure represents data on “characteristics of product formed”, which contains names, shown below:

Characteristics of Product Formed
Colour	White
Crystal Form	needles
Odor	none

As can be seen that data is measured in names, thus, the figure represents the qualitative data.
