What is the arithmetic mean?The sum of a group of numbersThe product of a group of numbersThe difference of a group of numbersThe quotient of a group of numbersQuestion 1 of 31 2. How is the arithmetic mean calculated?Multiplying the numbers and dividing by their countAdding the numbers and dividing by their countSubtracting the numbers and dividing by their countTaking the square root of the sum of squaresQuestion 2 of 31 3. How is the mode determined in a data set?It is the sum of all numbers divided by their countIt is the middle number in a sorted listIt is the value that appears most frequentlyIt is the product of all numbers in the setQuestion 3 of 31 4. In the example, why is the mode 6?It is the largest number in the setIt is the smallest number in the setIt appears most frequently in the setIt is the average of all numbers in the setQuestion 4 of 31 5. How is the median calculated in a data set with an even number of elements?It is the average of the two middle numbersIt is the sum of all numbers divided by their countIt is the middle number in the sorted listIt is the value that appears most frequentlyQuestion 5 of 31 6. What is the first step in calculating the median for an even number of elements in a dataset?Take the average of the two middle numbersArrange the data in ascending or descending orderFind the sum of all numbers in the datasetIdentify the mode in the datasetQuestion 6 of 31 7. Why is the 6th digit considered when calculating the median in this case?It is the largest number in the datasetIt is the smallest number in the datasetIt is the average of the two middle numbersIt helps to break ties in case of a modeQuestion 7 of 31 8. What is the final step in finding the median in this example?Divide the sum of all numbers by their countSubtract the smallest number from the largest numberAverage the two middle numbersFind the mode of the datasetQuestion 8 of 31 9.

Why is the least common factor used in the calculation of Harmonic Mean?To simplify the calculationTo find the product of valuesTo determine the medianTo ensure the mean is an integerQuestion 16 of 31 17. What is Mean Deviation (MD) in statistics?The arithmetic mean of all values in a datasetThe arithmetic mean of absolute deviations from the medianThe arithmetic mean of absolute deviations from the meanThe product of all values in a datasetQuestion 17 of 31 18. How is Mean Deviation calculated?Summing all deviationsSumming absolute deviationsFinding the median of the datasetMultiplying all values individually by their meanQuestion 18 of 31 19. What is the purpose of taking absolute values when calculating Mean Deviation?To simplify the calculationTo ensure all deviations are positiveTo find the median of the datasetTo determine the mode of the datasetQuestion 19 of 31 20. What is the Coefficient of Mean Deviation?The ratio of mean deviation to the medianThe ratio of mean deviation to the meanThe product of mean deviation and the meanThe ratio of standard deviation to the meanQuestion 20 of 31 21. What does the Coefficient of Mean Deviation (Mean) represent in statistics?The mean of absolute deviations from the medianThe ratio of mean deviation to the meanThe product of mean deviation and the meanThe mean of absolute deviations from the modeQuestion 21 of 31 22. How is the Coefficient of Mean Deviation (Mean) calculated?Dividing the sum of absolute deviations by the meanDividing the mean deviation by the meanMultiplying the mean deviation by the meanTaking the square root of the mean deviationQuestion 22 of 31 23. What is the primary purpose of the standard deviation in statistics?To find the mean of a datasetTo measure the spread or variability of a distributionTo calculate the median of a datasetTo determine the mode of a datasetQuestion 23 of 31 24. What does a small standard deviation indicate about the dataset?High consistency and homogeneityLow consistency and homogeneityHigh variability and diversityLow variability and diversityQuestion 24 of 31 25. Which of the following statements about standard deviation is true?It measures the central tendency of a distributionIt is calculated as the mean of absolute deviationsA large standard deviation indicates a high degree of consistencyIt is the product of all values in a datasetQuestion 25 of 31 26. What does the coefficient of variation (CV) measure?Central tendency of a distributionSpread or variability of a distributionProportion of the mean to the standard deviationRatio of the mean to the medianQuestion 26 of 31 27.
