I don't see how this is possible? how can you have a distrubution with no mean?
My professor says there is, but i don't get it...

A probability distribution without a mean refers to a situation where the mean, or average, of a set of data cannot be calculated. This can happen when the data set has extreme outliers or when the data is not normally distributed.
Yes, a probability distribution without a mean can still have a mode or median. The mode is the most frequently occurring value in a data set, and the median is the middle value. These measures of central tendency can still be calculated even if the mean cannot.
Knowing if a probability distribution has a mean or not can help in determining the appropriate statistical methods to use for analysis. If the data set has a mean, then measures of central tendency like the mean and standard deviation can be used. However, if the data set does not have a mean, then other measures, such as the median or interquartile range, may be more appropriate.
Yes, a probability distribution without a mean can still be symmetrical. The shape of the distribution is determined by the values in the data set, not just the presence or absence of a mean. It is possible for a data set to have a symmetrical distribution without a mean, such as in a uniform distribution.
A probability distribution without a mean can impact statistical analysis by limiting the types of analysis that can be performed. It may also make it more difficult to draw conclusions or make predictions about the data set. In some cases, it may be necessary to transform the data or use non-parametric methods of analysis instead.
