How can you get the mode of a grouped data if there are two classes that both have the highest frequency?

If there are more than one class intervals which have the same frequency (equally qualifying to be the mode class) then both of the classes will be the mode class. this is called bimodal.
However to calculate the mode of grouped data use the following formula
Mode = L + [ (F - F1) / { (F - F1) + (F - F2) } ] * h
where
L = Lower limit of the modal class
F = Frequency of the modal class
F1 = Frequency of the class immediately previous of modal class
F2 = Frequency of the class immediate next of modal class
h = Range of the modal class (higher limit - lower limit)
this is what i found out after reading books and understanding them. Please correct me if i am wrong.
Thanks,

What is the modal class in a grouped data if there are two classes with the same highest frequency?
They are both modal classes - the distribution is bi-modal.
How many advantages and disadvantages of cumulative frequency?
Advantages 1. C.F curves can be use to read off values both way round 2. The original information from a grouped frequency distribution can be onbtained from the C.F curves I dunno any disadvantages!!
What is the difference between a frequency histogram and a relative frequency histogram?
Both divide the data into discrete groups or intervals. The frequency histogram gives the number of times the data occur in the particular group or interval, while the relative frequency histogram gives the fraction of times the data occur in the particular group or interval.
Mary was both 13th highest and 13th lowest in a spelling contest?
Mary was 13 in a field of 25. She was then the 13th highest in the field from the bottom and 13th lowest from the top.
What is the measure of central tendency for nominal and ordinal data?
The mode can be used with both kinds of data. The median may be used with ordinal data but great care is required if the median falls between two classes of observations.The mode can be used with both kinds of data.

Do outliers change anything in a histogram?
Yes. They could increase the width and thereby reduce the frequency densities (heights) of the one or both of the outermost classes.

Both classes were wealthy. Both classes held seats in the senate and eventually both classes shared the counsulship.
