Question

The most commonly used distribution is in which the maximum frequency is at the central part and the frequency decreases when one moves away from the central part on either the left side or the right side.

Accepted Answer

Option a: Bell-shaped curve. Solution: Let us analyze the description of the curve: 1. The distribution has its maximum frequency at the central part. 2. As one moves away from the central part towards either the left side or the right side, the frequency decreases symmetrically. 3. This description corresponds to a symmetrical, single-peaked curve resembling a bell. 4. A Bell-shaped curve is the graphical representation of the normal distribution, which is the most commonly used continuous probability distribution in statistics. 5. Other curves like U-shaped (maximum frequency at the ends) and J-shaped (maximum frequency at one end) do not match this description. Hence, Option A is the correct answer.

The most commonly used distribution is ______ in which the maximum frequency is at the central part and the frequency decreases when one moves away from the central part on either the left side or the right side.
