Which of the following forms of variation will give a normal distribution?
Answer Details
Body weight is the form of variation that will give a normal distribution. A normal distribution, also known as a Gaussian distribution, is a type of probability distribution that follows a bell-shaped curve, where the majority of the values tend to cluster around the mean or average value. Body weight is a continuous variable, and the distribution of body weight in a large population tends to follow a normal distribution due to the combination of genetic and environmental factors influencing weight. On the other hand, blood groups, tongue rolling, and fingerprints are discrete variables, and their distribution does not follow a normal distribution.
