In the mean and the median pertaining to a certain character of a population arc of the same value, the following is most likely to occur:
Options
- Aa bi-modal distribution
- Ba T-shaped curve
- Ca skewed curve
- Da normal distribution.
Correct answer
D. a normal distribution.
Step-by-step solution
The normal distribution is a symmetrical, bell-shaped distribution in which the mean, median and mode are all equal. It is a central component of inferential statistics. The standard normal distribution is a normal distribution represented in z scores. It always has a mean of zero and a standard deviation of one.
Related Theory If one tail is longer than another, the distribution is skewed. These distributions are sometimes called asymmetric or asymmetrical distributions as they don't show any kind of symmetry. Symmetry means that one half of the distribution is a mirror image of the other half.
