  1. Question 1Recall

    Quantitative data is best described as data that is

    • anumerical, and can be counted or measured

    • dimpossible to apply to a larger population
  2. Question 2Skills & concepts

    A survey of 100 employees on monthly savings percentage shows 20 employees save 15%, 45 save 25%, 25 save 35%, and 10 save 45%. On a bar graph with a scale of 1 cm = 10 employees, the bar for the 25% savings category (45 employees) would be drawn

    • a4.5 cm tall
    • b2.5 cm tall
    • c45 cm tall
    • d2 cm tall
  3. Question 3Skills & concepts

    A jar of beads gives the raw data: red, green, blue, black, red, green, blue, yellow, red, red, green, green, green, yellow, red, green, yellow. Tallying this data, red appears 5 times and green appears 6 times, so in a frequency distribution table, the category with the highest frequency is

    • agreen, with a frequency of 6
    • bred, with a frequency of 5
    • cblue, with a frequency of 2
    • dyellow, with a frequency of 3
  4. Question 4Skills & concepts

    A survey collecting data through close-ended questions with fixed response options from a large number of respondents is best described as

    • aa quantitative data collection method (survey)
    • ba qualitative interview
    • ca focus group
    • ddocument analysis
  5. Question 5Recall

    The mode of a dataset is defined as

    • athe value or values that appear most frequently
    • bthe middle value when the data is arranged in order
    • cthe sum of all values divided by how many there are
    • dthe difference between the largest and smallest values
