Here's another example of how to read the Sample and Weighted numbers, for a question examining the number of children in a household:
Here's a sample crosstab, studying number of children in the household compared to how many of them buy a large number of batteries (20-29) per year:
"Of the people who ___[vertical column]___, ____% of them are ___[horizontal row]___."
The four-children row has asterisks next to it, so we won't look too closely at that row. See the Index video for what the asterisks mean.
"Of the people who ___[horizontal row]___, ____% of them are ___[vertical column]___."

Here's another example of how to read the Index numbers, for a question examining the likelihood that a larger number of children in a household = a larger number (20-29) of battery purchases:
The average for the Total row is set at 100. That's the average for the entire U.S. population, with or without any number of children.
