Identify any outliers in the following data set by first calculating the median and the interquartile range.

Number of texts sent Frequency Cumulative Frequency
0 10 10
1 8 18
0 5 23
0 3 26
0 1 27
Median I got was 14 (27/2 = 13.5 rounded up to 14) = score 1, please correct me if this is the incorrect way of finding the median.
For q1 and q2 answers say:
Q1 = 7th score = 0
Q3 = 21st score = 2

How the heck do I calculate Q1 and Q3 from the table without typing in each number one by one... Just need clarification on this, the rest I should be able to do, thanks.

Sorry, the table got messed up, but the first column lines up with "number of texts sent", second column, with frequency and last column with cumulative frequency.
Nvm Q1 is just 1/4 of the cumulative freq. and Q3 is 3/4 of the cumulative freq...
