Choose all the categorical data.

• height of a person

• hair color

• pencil color case

• time to go home

Answer explanation

Categorical data represents categories or groups. 'Hair color' and 'pencil color case' are categories, while 'height of a person' and 'time to go home' are numerical or continuous data, not categorical.

What is CATEGORICAL DATA?

• An example would be the number of students in a class.

• Data that can be measured or counted.

• Data that sorts variables into categories.

• It is also called QUANTATIVE DATA.

• It is also called QUALITATIVE DATA.

Answer explanation

Categorical data refers to data that sorts variables into distinct categories, making it also known as qualitative data. This type of data is not about measurement or counting, unlike quantitative data.

What is NUMERICALDATA?

• An example would be the number of students in a class.

• Data that can be measured or counted.

• Data that sorts variables into categories.

• It is also called QUANTATIVE DATA.

• It is also called QUALITATIVE DATA.

Answer explanation

NUMERICALDATA refers to data that can be measured or counted, such as the number of students in a class. It is also known as QUANTITATIVE DATA, distinguishing it from qualitative data that categorizes variables.

What are two types of NUMERICAL DATA?

• discrete

• nominal

• ordinal

• continuous

Answer explanation

Numerical data can be classified as discrete or continuous. Discrete data consists of distinct, separate values (like counts), while continuous data can take any value within a range (like measurements).

What are two types of CATEGORICAL DATA?

• discrete

• nominal

• ordinal

• continuous

Answer explanation

Nominal and ordinal are two types of categorical data. Nominal data represents categories without a specific order, while ordinal data has a defined order among the categories.

What type of graph is this?

• line plot

• column graph

• bar graph

• tally and frequency table

Answer explanation

The graph is a column graph (also known as a bar graph) as it uses vertical bars to represent data. Both terms are often used interchangeably, making them correct answers for this question.

What type of graph is this?

• line plot

• pie chart

• bar graph

• tally and frequency table

Answer explanation

The graph is a pie chart, which visually represents data as slices of a circle, showing proportions of a whole. This distinguishes it from line plots, bar graphs, and tally tables, which use different formats for data representation.

Looking at the tally and frequency table, What is the MODE?

Answer explanation

The mode is the value that appears most frequently in a data set. In this case, 'white' is the most common entry, regardless of capitalization, making it the mode. Therefore, the correct answer is 'white'.
