Respuesta :
A unimodal histogram is positively skewed if the right or upper tail is stretched out compared with the lower or left tail.
What is a unimodal histogram?
A histogram that only contains one "peak"—i.e., where the mode is only reached at a single value—is referred to as a unimodal histogram. The mode of the unimodal histogram is the singular value at which the histogram reaches a local maximum.
- The histogram is said to be left skewed if the "peak" of the histogram is located on the right side and the "tail" is located on the left side.
- If the histogram's "peak" is located on the left side and its "tail" is located on the right side, we define that the histogram is right-skewed.
- We may argue that the allocation is symmetric or that there is no skewness in the data if the "peak" of the histogram is located precisely in the middle and the data are dispersed symmetrically around the mode.
Therefore, a positively skewed unimodal histogram is when the right or upper tail is stretched out compared with the lower or left tail.
