Answer

Explanation:

Step1: Count row - categories

Count the number of non - total rows for seasons. There are 4 seasons (Summer, Spring, Fall, Winter), so there are 4 row - categories.

Step2: Count column - categories

Count the number of non - total columns for ages. There are 2 age groups (14 yr and 15 yr), so there are 2 column - categories.

Step3: Find number of 14 - year - olds who like winter

Look at the intersection of the "14 yr" column and "Winter" row. The value is 12.

Step4: Find total number of people polled

Look at the "Total" cell in the bottom - right corner of the table. Add the row - totals or column - totals. (45 + 8+14 + 15=82) or (47+35 = 82).

Answer:

How many categories are shown in the rows? 4 How many categories are shown in the columns? 2 How many 14 - year - olds consider winter their favorite season? 12 How many people total were polled? 82
