If the data are skewed, which option of central tendency measure is the most unreliable indicator?

If the data are skewed, which option of central tendency measure is the most unreliable indicator? Correct Answer Mean

Explanation

The mean is the most popular and well-known measure of central tendency. It can be used with both discrete and continuous data. Although its use is most often 

with continuous data. The mean is equal to the sum of all the values in the data set divided b the number of values in the data set

Mean = ∑xi/N

N = number of observation

X = observation

 \TIMES C

C = Size of the interval

F1 = Frequency of the modal class

F2 = Frequency of the class succeeding the modal class

F0 = Frequency of the class preceding the modal class

L = Lower limit of the modal class

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create anapplication. The application uses the ADO.NET Entity Framework to model entities. Theapplication allows users to make changes to entities while disconnected from the central data store. You need to ensure that when the user connects to the central data store and retrieves new data, the application meets the following requirements:
  • Changes made to the local data store in disconnected mode are preserved.
  • Entities that have already been loaded into the local data store, but have not been modified by the user, are updated with the latest data.
