Q.2.131 - Elementary Statistics

Question

Identify and sketch three distribution shapes that are symmetric

Step-by-Step Solution

Answer

1-Bell shaped distribution

2-normal distribution

3-Triangular distribution

Step-1: Given Information

We have to Identify and sketch three distribution shapes that are symmetric.

Step-2: Explanation

If the shape of any distribution is divided into two parts, one of which is the mirror image of the other, the distribution is said to be symmetric. The following are some examples of symmetric distribution:

1. Bell-shaped distribution. The normal distribution,, frequently known as the bell curve, is a regular state variable circulation. A "bell curve" is an evenly ringer molded twist that is utilized to show a normal distribution on a chart. 

The bell-shaped distribution is depicted in the diagram below.

2. Uniform distribution: In statistics, a uniform distribution is a sort of probability distribution in which all outcomes have the same probability.

The following is a diagram of uniform distribution:

3.  A triangular continuous probability distribution with a triangle-shaped probability density function. The minimum value a, the highest value b, and the peak value c are the three values that characterize it. 

The following is a diagram of triangular distribution:
