Final answer:
There should be one row per every participant or category on the scoring sheet, used for recording statistical data such as goals per game. For tests of independence, expected numbers are calculated using the row and column totals, divided by the total surveyed.
Step-by-step explanation:
On the scoring sheet, there should be one row per every participant or unit being analyzed. When recording data for statistical purposes such as testing for independence in mean goals scored per game for different soccer teams, each row usually represents an individual data point or a specific category.
To perform a test of independence, you would calculate expected numbers. This involves taking the row total and multiplying it by the column total, and then dividing by the total number surveyed. This is a key step in statistical analysis to determine whether observed frequencies differ significantly from expected frequencies.
