Can you explain what a normal distribution curve is?
Sure! A normal distribution curve is a bell-shaped graph that represents the distribution of a set of data. It shows how values are spread around the mean.
What are the key characteristics of a normal distribution?
The key characteristics include symmetry around the mean, the mean, median, and mode being equal, and about 68% of the data falling within one standard deviation from the mean.
Why is the normal distribution important in statistics?
It's important because many statistical tests assume normality, and it helps in understanding probabilities and making predictions.
Can you give me an example of where normal distribution is used?
Certainly! It's commonly used in fields like psychology for test scores, in finance for stock returns, and in quality control for manufacturing processes.
