Data analysis (tables, graphs, trends) on the SSAT Upper Quantitative (Math) section asks students to read tables and charts, work with means and medians, and revise survey counts after a change of category.
A student must find a missing list value from a stated mean, then identify the median; update notebook and binder tallies and report a fraction; and turn a pie-chart sector of one fifth of the data into a central angle.
Questions are short multiple-choice items whose wrong choices often swap mean with median, skip the new total after students switch, or treat a sector fraction as an angle instead of scaling it around the circle.
Sample questions
Pick an answer to see whether it is right — nothing is saved, and nothing needs an account.
Question 1Mid
The numbers 8,11,14,17, and x have a mean of 14. What is the median of the five numbers?
Show answer
Answer: B — 14
The total of the five numbers is 5×14=70. The known numbers add to 50, so x=20. In order, the numbers are 8,11,14,17,20, and the median is 14.
Question 2Easier
A class survey showed 18 students chose spiral notebooks, 12 chose composition notebooks, and 10 chose binders. Then 5 students who chose composition notebooks changed their choice to binders. After the change, what fraction of the students chose binders?
Show answer
Answer: C — 83
There are 18+12+10=40 students in all. After 5 students switch to binders, 15 students choose binders. The fraction is 4015=83.
Question 3Easier
In a pie chart, a sector represents 51 of the data. What is the measure of the central angle of the sector?
Show answer
Answer: C — 72∘
A full circle is 360 degrees, so one fifth is 360÷5=72 degrees.
