A mode is a statistical measure that represents the most frequently occurring value or observation in a data set. It is also known as the peak of a distribution.
Unlike mean and median which represent the central tendency of a data set, mode represents the most common value. It is not affected by extreme values and is useful for categorical or discrete data.
Yes, a data set can have more than one mode if there is more than one value that occurs with the same frequency and is higher than other values in the data set.
Mode is useful in data analysis as it helps to identify the most common value in a data set and understand the distribution of the data. It is also helpful in identifying outliers and anomalies in the data.
No, mode is not affected by the size of the data set as it only depends on the frequency of values. It can be calculated for both small and large data sets.
