A bell-shaped curve, also known as a normal distribution or Gaussian distribution, is a symmetrical probability distribution in statistics. It represents a graph where the data clusters around the mean, with the highest frequency in the center, and decreases gradually towards the tails. Properties of normal distributionThe Gaussian distribution, (also known as the Normal distribution) is a probability distribution. Its bell-shaped curve is dependent on μ, the mean, and σ, the standard deviation ( σ 2 being the variance). f ( x, μ, σ) = 1 σ 2 π e − ( x − μ) 2 2 σ 2. The peak of the graph is always located at the mean and the area under the curve ...Choose the correct graph below. (i) Construct a relative frequency histogram of the data.

They are evenly spaced, with 2 as the mean (1 + 2 + 3 / 3 = 6 / 3 = 2). If you add a number to the far left (think in terms of adding a value to the number line), the distribution becomes left skewed: -10, 1, 2, 3.1. Bell-Shaped. A histogram is bell-shaped if it resembles a "bell" curve and has one single peak in the middle of the distribution. The most common real-life example of this type of distribution is the normal distribution. 2. Uniform.
