All it means that there were more than one observations which had the same value.
well it depends on what tsunami you mean, there is more than one...
There is (or should be) a key stating which number means liked more and which meant liked less. There is no universal rule about that.
You will need to explain the question in more detail. What do you mean by finding the mean of a number? The mean of a number is just that number. Did you intend the mean of a set of numbers? And if so, how many?
If the same number does not occur more than once in a data set, it means that all values are unique. In such cases, the mode, which is the number that appears most frequently, would not exist because no number meets the criterion of appearing more than once. Therefore, a data set with all unique values is said to have no mode.
The number plus sevenIf the "number" is X, then seven more than X is X+7

A single number cannot have a mean - other than itself. To calculate a mean, you need more than a single number.
Probability is a measure of the expectation that an event will occur or a statement is true. Probabilities are given a value between 0 (will not occur) and 1 (will occur).[1] The higher the probability of an event, the more certain we are that the event will occur.
In probability theory, disjoint events are two (or more) events where more than one cannot occur in the same trial. It is possible that none of them occur in a particular trial.
Six more than the number means "the number" + 6.

A group of two or more numbers has a 'mean'. A single number doesn't.If you absolutely must have the mean of a single number, it's that number itself.
If the same number does not occur more than once in a data set, it means that all values are unique. In such cases, the mode, which is the number that appears most frequently, would not exist because no number meets the criterion of appearing more than once. Therefore, a data set with all unique values is said to have no mode.
You cannot find the mean for this number unless you have more information.
