  1. Which type of data is best represented by a histogram?

    Answer: Continuous numerical data

    Histograms display the frequency distribution of continuous numerical data by grouping values into intervals called bins.

  2. In a dataset, the value that appears most frequently is called the:

    Answer: Mode

    The mode is the value that occurs most often in a dataset and is the only measure of central tendency applicable to nominal data.

  3. A correlation coefficient of -0.85 between two variables indicates:

    Answer: A strong negative relationship

    A correlation coefficient near -1 indicates a strong negative relationship, meaning as one variable increases, the other decreases.

  4. Which measure of spread is most affected by extreme outliers in a dataset?

    Answer: Range

    The range is calculated solely from the maximum and minimum values, making it the most sensitive measure to outliers.

  5. When analyzing a pie chart, the angle of each slice is proportional to:

    Answer: The percentage each category represents of the whole

    Each slice in a pie chart represents a proportion of the total (360°), so its angle equals the category's percentage multiplied by 360.

  6. A p-value of 0.03 in a statistical test typically means:

    Answer: The result is statistically significant at the 0.05 level

    A p-value of 0.03 is below the common 0.05 threshold, indicating the result is statistically significant and unlikely due to chance alone.
