Data that cannot be written as numbers are called what?

  1. Quantitative data
  2. Qualitative data
  3. Continuous data
  4. Discrete data
Show answer and solution

Correct answer: B. Qualitative data

1. Data are the pieces of information observed and recorded from an experiment or a survey. 2. Qualitative data are data that cannot be written as numbers. 3. The two common types of qualitative data are categorical data and anecdotal data. 4. Quantitative data are the opposite, since those are data that can be written as numbers. _Source: Siyavula Mathematics Grade 10 (Everything Maths, CC BY 4.0), Chapter 10: Statistics_

A survey records how many learners sit in each classroom. What type of data is collected?

  1. Quantitative continuous
  2. Qualitative anecdotal
  3. Quantitative discrete
  4. Qualitative categorical
Show answer and solution

Correct answer: C. Quantitative discrete

1. Each recorded value is a number, so the data are quantitative. 2. Discrete quantitative data can be represented by integers and usually occur when we count things. 3. A count of learners can only ever be a whole number. 4. Continuous data can take any real value, which fits heights and masses rather than counts. _Source: Siyavula Mathematics Grade 10 (Everything Maths, CC BY 4.0), Chapter 10: Statistics_

How is the mean of a data set calculated?

  1. Count divided by the sum
  2. Sum multiplied by count
  3. Largest minus the smallest
  4. Sum divided by the count
Show answer and solution

Correct answer: D. Sum divided by the count

1. The mean is one of the three measures of central tendency. 2. It is the sum of a set of values, divided by the number of values in the set. 3. The mean is sometimes also called the average or the arithmetic mean. 4. Subtracting the smallest value from the largest gives the range, which measures spread instead. _Source: Siyavula Mathematics Grade 10 (Everything Maths, CC BY 4.0), Chapter 10: Statistics_
