it varies between cars.

Advantages:Linear unbiased estimate of central tendencyThe arithmetic mean has a Gaussian (Normal) distribution which is well studiedMany robust methods to test for equality of (difference between) meansDisadvantages Cannot be used for qualitative dataMore difficult to calculate than some other measures of central tendencyMay be affected by outliersMay not be a value that can be realised: for example, the mean number of cars per household on my street is 1.7, but nobody has or can have 1.7 cars!

Total frequency describes how many times an event occurs. For example, between 1 and 2 pm on a certain date, the number of cars passing through a specific intersection was 389. On the other hand, the mean is an average measures describing the central tendency of an event. For example, The average number of cars passing through a specific intersection between 1 and 2 pm is 376. That means sometimes it is more than 376, sometimes it is less, but 376 is the mean or average figure. In statistical research the mean is widely used, usually accompanied by the standard deviation, which shows the amount of variation from the mean. A small standard deviation means that the mean is a fairly reliable estimate of the frequency of an event. A large standard deviation means that there can be a significant difference between the mean of an event and any one occurrence of it.

they are the same cars!! its just the x stands for the roman numeral 10.
