  1. In a GAT data interpretation question, a bar chart shows sales for four quarters. Which quarter had the highest sales if the bars reach 40, 65, 55, and 70 respectively?

    Answer: Quarter 4

    Quarter 4 has the tallest bar at 70, which is higher than all other quarters (40, 65, 55).

  2. Which measure of central tendency is MOST affected by extreme outlier values in a dataset?

    Answer: Mean

    The mean is calculated using every value in the dataset, so a single extreme outlier can significantly shift it up or down.

  3. A researcher surveys 50 randomly chosen students out of a school of 500. This survey represents a:

    Answer: Random sample

    A random sample is one in which every member of the population has an equal chance of being selected, as described here.

  4. On a GAT data table, the row totals add up to 120 and the value in one cell is 30. What percentage of the total does that cell represent?

    Answer: 25%

    30 ÷ 120 = 0.25, which equals 25% of the total.

  5. Which type of research design examines the relationship between variables without manipulating them?

    Answer: Correlational

    Correlational research measures and observes variables to see if they are related, without controlling or manipulating any variable.

  6. A pie chart shows five categories totaling 100%. If one slice is labeled 35%, what fraction of the whole does it represent?

    Answer: 7/20

    35% = 35/100 = 7/20 when reduced to its simplest form.
