Which of the following is the shape of a normal curve?
Answer:
A normal curve, also known as a Gaussian distribution, has a bell-shaped curve. The normal distribution is symmetrical around the mean and follows a specific pattern where the data is evenly distributed around the mean. The curve is characterized by its smooth, symmetric, and unimodal shape, meaning it has one peak at the mean. In a normal curve, 68% of the data falls within one standard deviation from the mean, 95% within two standard deviations, and 99.7% within three standard deviations. This distribution is commonly used in statistics to represent real datasets and is essential for many analytical processes such as hypothesis testing and confidence interval estimations.
