Can a distribution have two medians?
We can never have two medians since the data always includes a single median value and a single mean value. Mode, however, can have more than one value. The mode corresponds to the highest peak and is the most frequent number. A bimodal distribution is an exception.
How do you know if a distribution is bimodal?
When two clearly separate groups are visible in a histogram, you have a bimodal distribution. Literally, a bimodal distribution has two modes, or two distinct clusters of data.
Can a normal distribution be bimodal?
A mixture of two normal distributions with equal standard deviations is bimodal only if their means differ by at least twice the common standard deviation.
Can histogram be bimodal?
A histogram that is bimodal has two peaks or two highest main points. These points are not necessarily of the same height. The two peaks mean that there are two groups in the frequency table that has the most frequency of occurrence.
