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

    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 correct answer is "mean" because it is another word for average. The mean is calculated by finding the sum of all the data points and then dividing it by the number of items in the data set.

    The middle number in a set of data that has been ordered least to greatest - ProProfs

    The middle number in a set of data that has been ordered least to greatest

    • Range

    • Mean

    • Median

    • Mode

    Correct Answer
    A. Median
    Explanation
    The median is the middle number in a set of data that has been ordered from least to greatest. It is found by arranging the data in ascending order and selecting the number that falls in the middle. The median is a measure of central tendency and is useful in determining the typical or average value in a dataset. Unlike the mean, the median is not affected by extreme values, making it a more robust measure in certain situations.

    Which of the following measurement scale is said to have imprecise differences between consecutive values, but have a meaningful order to those values, and permit any order-preserving transformation? - ProProfs

    Which of the following measurement scale is said to have imprecise differences between consecutive values, but have a meaningful order to those values, and permit any order-preserving transformation?

    • Nominal

    • Ordinal

    • Interval

    • Ratio

    Correct Answer
    A. Ordinal
    Explanation
    Ordinal measurement scale is said to have imprecise differences between consecutive values, but have a meaningful order to those values, and permit any order-preserving transformation. This means that the values can be ranked or ordered, but the differences between the values may not be equal or precise. Additionally, any order-preserving transformation can be applied to the values without affecting the meaningful order.

    Which of the following measurement scale is said to be measurements that do not have meaningful rank order among values, and permit any one-to-one transformation? - ProProfs

    Which of the following measurement scale is said to be measurements that do not have meaningful rank order among values, and permit any one-to-one transformation?

    • Nominal

    • Ordinal

    • Interval

    • Ratio

    Correct Answer
    A. Nominal
    Explanation
    Nominal measurement scale is considered to have measurements that do not have a meaningful rank order among values, and permit any one-to-one transformation. This means that the values in a nominal scale cannot be ranked or ordered in any meaningful way, and they can be transformed or re-labeled without changing the underlying data. In contrast, ordinal, interval, and ratio scales have a meaningful rank order among values and do not permit arbitrary transformations.

  • 6. 
    Which of the following measurement scale is said to have meaningful distances between measurements defined, but the zero value is arbitrary (as in the case with longitude and temperature measurements in Celsius or Fahrenheit), and permit any linear transformation? - ProProfs

    Which of the following measurement scale is said to have meaningful distances between measurements defined, but the zero value is arbitrary (as in the case with longitude and temperature measurements in Celsius or Fahrenheit), and permit any linear transformation?

    • Nominal

    • Ordinal

    • Interval

    • Ratio

    Correct Answer
    A. Interval
    Explanation
    The interval measurement scale is said to have meaningful distances between measurements defined, but the zero value is arbitrary. This means that the values on this scale can be compared and the differences between them are meaningful, but there is no true zero point. Examples of interval scales include temperature measurements in Celsius or Fahrenheit, where the zero point is arbitrary and does not indicate the absence of temperature. Additionally, interval scales permit any linear transformation, meaning that the values can be multiplied or divided by a constant without changing the nature of the scale.

    Which of the following is defined as the amount by which an observation differs from its expected value? - ProProfs

    Which of the following is defined as the amount by which an observation differs from its expected value?

    • Statistical error

    • Mean squared error

    • Significant

    • Regression

    Correct Answer
    A. Statistical error
    Explanation
    Statistical error is defined as the amount by which an observation differs from its expected value. It represents the discrepancy between the observed data and the predicted or expected values. It is often used in statistical analysis to measure the accuracy of a model or estimate. Mean squared error, significant, and regression are not specifically defined as the amount by which an observation differs from its expected value.

    Using the word "data" to mean "transmittable and storable computer information" was first done  in what year? - ProProfs

    Using the word "data" to mean "transmittable and storable computer information" was first done  in what year?

    • 1977

    • 1936

    • 1946

    • None of the above

    Correct Answer
    A. 1946
    Explanation
    The word "data" was first used to refer to "transmittable and storable computer information" in the year 1946.

    Rate this question:

  • 9. 
    In what year was the word "data processing" first used? - ProProfs

    In what year was the word "data processing" first used?

    • 1946

    • 1948

    • 1954

    • 1964

    Correct Answer
    A. 1954
    Explanation
    The word "data processing" was first used in the year 1954.

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

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

    • Title

    • Interval

    • Frequency

    • Label

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