find mode

Question

anonymous · Answer

are you sure youre trying to find the mode? Mode is the number that occurs most often and all the numbers occur only once so there is no mode

anonymous · Answer

yes i need to find mode

anonymous · Answer

what do the fi and xi stand for
?

e.mccormick · Answer

Do you understand the relationship between frrequency and mode?

anonymous · Answer

yes

anonymous · Answer

what i think is that,

From the table, we can easily observe that the observation 40 has maximum frequency which is 10.
Thus, the mode of the given data is 40.

but i m not sure abt this answer

anonymous · Answer

$$mode = L + \left(\begin{matrix}f^1-f^0 \ 2f^1-f^0-f^2\end{matrix}\right)$$

Yah, look at Mode for Grouped Data on this: http://www.wyzant.com/help/math/statistics_and_probability/averages It expands what Tessa_Mae said.

but u know the pblm is the class intervals are not continuous series

anonymous · Answer

otherwise i know abt this formula

e.mccormick · Answer

Yah, I wondered about that.  It makes me unsure.  Don't know if that is standard notation or not and what it means.  Looks like the issue is finding out what that xi notation means.

anonymous · Answer

xi is the class interval

e.mccormick · Answer

Yes.  But what does the notation of having non-range values in a line mean?

anonymous · Answer
