    Correct Answer
    A. Outlier
    Explanation
    An outlier is a piece of data that is significantly different or separate from the rest of the data. It is an observation that lies an abnormal distance from other values in a random sample from a population. Outliers can be caused by various factors such as measurement errors, data entry errors, or genuine extreme values. Identifying and analyzing outliers can provide valuable insights into the data and help detect anomalies or unusual patterns.

    The vertical number line on a graph

    • Title

    • Label

    • X-axis

    • Y-axis

    Correct Answer
    A. Y-axis
    Explanation
    The vertical number line on a graph is called the y-axis. It is used to represent the dependent variable or the variable being measured or observed. The y-axis is typically labeled with units of measurement and represents the values of the dependent variable. By plotting points on the graph along the y-axis, we can visually analyze the relationship between the dependent variable and the independent variable(s) represented on the x-axis.

    Correct Answer
    A. X - axis
    Explanation
    The x-axis is the horizontal number line on a graph that represents the independent variable or the variable being measured or controlled. It is used to plot the values of the independent variable and provides a reference for locating points on the graph. By placing the independent variable on the x-axis, it allows for a clear visualization of the relationship between the independent and dependent variables.

    • Bar graph

    • Histogram

    • Line plot

    • Stem-and-leaf plot

    Correct Answer
    A. Histogram
    Explanation
    A histogram is a graphical representation that uses bars to show the frequency of data that has been organized into intervals. It is commonly used to display the distribution of numerical data. Each bar represents a specific interval, and the height of the bar represents the frequency or count of data points within that interval. Histograms are useful for visualizing the shape and spread of data, making it easier to identify patterns and understand the distribution of values.

    Another word for average - The sum of the data divided by the number of items in the data set.

    • Range

    • Mean

    • Median

    • Mode

    Correct Answer
    A. Mean
    Explanation
    The term "mean" is another word for average. It is calculated by summing up all the data values and then dividing the sum by the number of items in the data set. This gives us a measure of central tendency that represents the typical value of the data set.

    Rate this question:

  • 19. 

    Groups of numbers - This information goes on the x-axis of a histogram.

    • Interval

    • Frequency

    • Label

    • Title

    Correct Answer
    A. Interval
    Explanation
    In a histogram, the x-axis represents the groups of numbers, also known as intervals, that are being analyzed or measured. Each interval represents a range of values, and the frequency of occurrence of those values is depicted on the y-axis. Therefore, the correct answer is "interval" as it accurately describes the information that is plotted on the x-axis of a histogram.

    Rate this question:

  • 20. 

    Numbers called _____ can be used to describe the center of data.

    • Measures of central tendency

    • Data

    • Intervals

    • Scale

    Correct Answer
    A. Measures of central tendency
    Explanation
    Measures of central tendency, such as mean, median, and mode, are numerical values that represent the center of a dataset. These measures provide information about the typical or average value of the data. By calculating and analyzing these measures, we can gain insights into the central or typical values of a dataset, which can help in understanding the overall pattern or distribution of the data. Therefore, measures of central tendency can be used to describe the center of data.
