Guide to Two way tables: Explanation, Diagrams & Worked Examples

Download Printable One Page Guide (PDF)

Explanation:

A two-way table sorts data into rows (one category) and columns (a second category). Every row adds across to its Row Total on the right, every column adds down to its Column Total at the bottom, and both sets of totals add to the Grand Total in the bottom-right corner.

Start with any row or column that has only one missing value, subtract from the total to fill it in, and repeat until every cell is complete. Read probability questions carefully to check the denominator.

Example 1: Complete the two-way table for 80 students choosing French or Spanish (bold numbers are the missing answers).

FrenchSpanishTotal
Year 10182745
Year 11142135
Total324880
Y10 Spanish = 45 − 18 = 27; Y11 French = 32 − 18 = 14
Y11 Total = 80 − 45 = 35; Spanish Total = 27 + 21 = 48

Example 2: Using the completed table in Example 1:
(a) Find the probability a random student studies Spanish.
(b) A Year 11 student is chosen at random. Find P(French).

Solution:

(a) Out of all 80 students, 48 study Spanish:
P(Spanish) = 4880 = 35
(b) Out of the 35 Year 11s, 14 study French:
Answer: (a) 4880   (b) 1435 (or 25)
