The range of a dataset is the difference between its highest and lowest values. For the given data set (15, 22, 34, 11, 45, 67, 88), the maximum value is 88 and the minimum value is 11. Subtracting the minimum from the maximum gives 88 minus 11, which equals 77.
The range of a dataset is the difference between its highest and lowest values. For the given data set (15, 22, 34, 11, 45, 67, 88), the maximum value is 88 and the minimum value is 11. Subtracting the minimum from the maximum gives 88 minus 11, which equals 77.
In descriptive statistics, measures of dispersion include range, variance, standard deviation, and mean deviation, which quantify the spread or variability of data points.
The range is calculated as Maximum value minus Minimum value.
Maximum value in the given dataset is 88.
Minimum value in the given dataset is 11.
Option B (88) is the maximum value of the dataset, not the range.
Option C (11) is the minimum value of the dataset, not the range.
Option D (76) is an incorrect calculation result.
A is correct тАФ The range of the dataset is 77, calculated by subtracting the minimum value (11) from the maximum value (88).
Questions on measures of central tendency and dispersion frequently appear in railway and competitive exams, often combining mean, median, mode, and standard deviation calculations.
