  • Which scale will you use to measure the temperature(Fahrenheit or Celsius)?
    1. ordinal scale
    2. interval scale
    3. ratio scale
    4. nominal scale

  • Which of the following best describes an ordinal scale?
    1. A scale that ranks data in order from lowest to highest.
    2. A scale that allows for negative values.
    3. A scale that uses numbers to represent categories or labels.

  • Which of the following describes a Random Error?
    1. An error that occurs due to a mistake in the measurement process.
    2. An error that consistently causes the measurements to be higher or lower than the true value.

  • Which of the following best describes a biased error?
    1. An error that consistently causes the measurements to be higher or lower than the true value.
    2. An error that occurs due to a mistake in the measurement process.
    3. An error that is introduced by the sample selection process.
    4. An error that occurs randomly and can affect the accuracy of data.

  • Which of the following describes an ordinal scale?
    1. A scale that uses numbers to represent categories or labels.
    2. A scale that allows for negative values.
    3. A scale that ranks data in order from lowest to highest.

  • Which of the following is the benefit of using primary data?
    1. It is less time-consuming than secondary data
    2. It is more specific to the research question
    3. It is readily available
    4. It is less expensive than secondary data

  • Which of the following represents an instance of secondary data?
    1. Focus group discussions conducted by a researcher
    2. Survey data collected by a researcher
    3. Interviews conducted by a researcher
    4. Census data collected by the government

  • What is a biased error in research?
    1. It is the result of inaccurate measurement tools.
    2. It is the random variation of results due to chance
    3. It is the systematic distortion of results due to flaws in the study design or methodology

  • Which of the following represents an example of primary data?
    1. A research report published by a university
    2. A survey conducted by a researcher

    1. Time
    2. None of the above
    3. Quantitative values
    4. Categories or Groups

  • What is the purpose of a bar chart?
    1. To show relationships between two variables
    2. To compare data across different categories
    3. To show how data changes over time

  • Which of the following represents an example of non-random sampling?
    1. Convenience sampling
    2. Simple random sampling
    3. Cluster sampling
    4. Stratified random sampling

  • In a component bar chart, what is the purpose of the stacked bars?
    1. To show how data changes over time
    2. To show different components of the total value
    3. To show relationships between two variables
