A table classifies 200 employees of a firm in Bengaluru by gender (male, female) and by department (Finance, Marketing, Operations). How many cells for data (excluding totals) does this table have, and what type of table is it?

The table has 6 data cells because 2 genders times 3 departments equals 6. Because two characteristics are classified together, it is a two-way, or manifold, table rather than a simple one-way table.

  1. A5 cells; simple table
  2. B6 cells; two-way (manifold) tableCorrect
  3. C6 cells; one-way table
  4. D5 cells; two-way table

Explanation

Two gender categories times three departments gives 2 × 3 = 6 data cells. Since two characteristics are classified at once, it is a two-way (manifold) table, not a simple one-way table. The 5-cell options wrongly add the categories (2 + 3).
