The "mode" is the most commonly-occurring number in a data set (if there is one). For example, for the set: 2, 3, 3, 5, 5, 5, 7, 8 the mode would be 5. I'm not sure what your numbers are: do you have 15 people under (age) 10? To answer this, we need to know what the numbers in the data set are...
i've posted all the information and this is one s grouped frequency
I just found this web page; it may be helpful to you: https://www.mathsisfun.com/data/frequency-grouped-mean-median-mode.html

thanks@onemathcat
but my question is for finding mode by the formula we consider 109 to be the maximum frequency?
not a stats person |dw:1442645270107:dw|
@triciaal icalculated the mode .is it 50.99
the mode is just the most frequent for each group what amount is in that group
0-10 15 10-20 17 20-30 19 30-40 27 40 -50 19 50-60 12 mode 27 group 30 - 40
the frequencies given are they cummulative frequency
you said that above or did I misunderstand?
nope i'm asking you i did not understand ;coz in the question it does not says anything
@ganeshie8 stats?
look at your first post below the question
I am not the best stats person @nincompoop
The label "year under" seems to indicate a cumulative frequency table. Converting to a frequency table we get: Age group 0 ~ 9 10 ~ 19 20 ~ 29 30 ~ 39 40 ~ 49 50 ~ 59 No. persons 15 17 19 27 19 12 The largest group is in the 30 ~ 39 age range. The average age in this group can be estimated to be given by (30 + 39)/2 = 34.5 years old. Therefore the estimated mode is 34.5 years of age.
