Variability Services are highly variable because the quiality of service depends on who provides and where and when they are provided.
The level of service provided suring peak season may differ from the service provided during off-peak season if consistency is not being practiced.
For example, when there is less number of customers, services are more specific and polite. If there is large number of customers, service provider tend to be busy and might lose some service to the customers.
Variability can also means lack of consistency.
For example, if one day you eat in a restaurant, the food and service was very good but the next day, it becomes bad.

Climate variability is unknown
The usual measures of variability cannot.
Yes. The greater the range, the greater the variability.
minimizes the within-class variability while at the same time maximizing the between-class variability.
P. 60 of the text Operations Management by William J. Stevenson states "...because it involves intellectual activities and a high degree of variability." It seems that in services we need to investigate what the problem is and formulate the solution. There can be variability in the problem and in the solution. This consulting or investigating doesn't occur in manufacturing. In manufacturing a company knows what its product is and it simply creates it with little to no variability.
Why are measures of variability essential to inferential statistics?
An indication of how widely spread or closely clustered the data values are. Range, minimum and maximum values, and clusters in distribution give some indication of variability.
