Does A symmetrical distribution have a variation.?

Yes, a symmetrical distribution can have variation. Variation refers to the spread of data points around the mean, which can be quantified using measures like variance or standard deviation. Even in a perfectly symmetrical distribution, such as a normal distribution, the data can vary widely; it simply means that the distribution of data points on either side of the mean is balanced.
