Step 1: Understand the meaning of mode.}
Mode is a measure of central tendency. It tells us the value that appears most frequently in a set of observations or a frequency distribution.
Step 2: Define it for frequency distribution.}
In a frequency distribution, the mode is the value or observation which has the highest frequency.
Step 3: Explain its importance.}
It helps us identify the most common item or the most repeated value in the given data.
Step 4: State the formal definition.}
Therefore, the mode of a frequency distribution is the observation corresponding to the maximum frequency.
Step 5: Final answer.}
Hence, mode is defined as the value which occurs most frequently in the frequency distribution.
