Discrete or Continuous

Give an example of a discrete variable.

• The number of animals per household.

• The weight of a person in kilograms.

• The height of a tree in meters.

• The temperature in degrees Celsius.

What is a continuous variable?

• A type of qualitative variable that can take on a limited number of values.

• A type of quantitative variable that can take on an infinite number of values within a given range.

• A variable that can only take on whole number values.

• A variable that does not change over time.

What type of data is represented by the mass of each animal in a herd?

• Categorical data

• Discrete data

• Continuous data

• Nominal data

Is the number of TV programmes watched in the last month discrete or continuous?

• Discrete

• Continuous

• Both discrete and continuous

• Neither discrete nor continuous

How do you determine if a variable is discrete or continuous?

• If the variable can take any value within a range, it is discrete.

• If the variable can only take specific values, it is continuous.

• If the variable can only take specific values (like whole numbers), it is discrete.

• If the variable can take only negative values, it is continuous.

What is a discrete variable?

• A variable that can take on any value within a given range.

• A type of quantitative variable that can take on a countable number of values.

• A variable that is not measurable and cannot be counted.

• A variable that can only take on two values, such as true or false.

What is the significance of understanding discrete vs continuous variables?

• It helps in choosing the right statistical methods and tools for data analysis.

• It determines the type of data visualization to use.

• It affects the sample size required for experiments.

• It influences the interpretation of qualitative data.

What is an example of a situation where you would collect discrete data?

• Counting the number of students in a classroom.

• Measuring the height of a plant in centimeters.

• Recording the temperature every hour.

• Tracking the distance traveled by a car in kilometers.

Is the time taken to travel to school discrete or continuous?

• Discrete

• Continuous

• Categorical

• Nominal

What is the difference between qualitative and quantitative data?

• Qualitative data represents numerical values, while quantitative data describes characteristics or qualities.

• Qualitative data describes characteristics or qualities (e.g., colors, names), while quantitative data represents numerical values (e.g., height, weight).

• Qualitative data is always more accurate than quantitative data.

• Quantitative data is subjective, while qualitative data is objective.
