• Data analysis and results:

Q1 - in P2Q2 sheet, choose any suitable quantitative variable (use the raw data), then:

A-compute the three measures of central tendency and interpret the values.?

B- compute the skewness values and conclude the data distribution.?

i have to complete my part of group assignment, and my part is to compute the mean median mode for Q1 section A.

And also i have to interpret the measurement too Q1 section B for skewness.

----------

and this is the data of my groupmate that i have to follow up with.
