Which of the following is a measure of central tendency that is affected by extreme values in a dataset?
Median
Mode
Mean
Range
Option (3) is correct as the mean is a measure of central tendency that is calculated by adding up all the values in a dataset and dividing by the number of values. Extreme values in a dataset can significantly affect the mean.
Option (1) is incorrect as the median is not affected by extreme values in a dataset, as it is the middle value when the dataset is arranged in order.
Option (2) is incorrect as the mode is the value that occurs most frequently in the dataset and is not affected by extreme values.
Option (4) is incorrect as the range is the difference between the maximum and minimum values in a dataset and is not a measure of central tendency.
