Suppost we have a dataset as below: (Value,Frequency) pairs: (1,2), (2,4), (3,6), (4,8), (5,10)

Can we say that this data is normally distributed, or have a normal distribution for this dataset?

    There seems to be no connection with any normal. The rlationship is linear.2012-06-19

    They look like a straight line, not a bell curve ...2012-06-19

    They don't look at all like a normal distribution, but it is just possible that these results could come from a sample from a normal distribution (very unlikely, I would think) - you could do a hypothesis test to see if it is so unlikely as to be "negligible".2012-06-19

    I do agree with you, and it is what I think. But in Gaussian Naive Bayes, it is simply supposed that each feature has a gaussian distribution on our class. I am wondering how we can assume that without even observing the data and suppose that all the features can have a Gaussian distribution...2012-06-19
