What does it mean to understand data to normalize?
Understanding data to normalize means understanding universes and units of analysis. In working with Census Bureau data for example, it is important to become familiar with a data item's universe: In other words, the value or population that forms the base from which the data item in question is a subset. Therefore, if you want to create

Should a normalized weight be 5% or 1%?
To make corrections once again, some normalized weight users adopt a rule of thumb and use a more conservative significance level (1% instead of 5%) before declaring a significant result. Normalized weights: Is using them enough? SAS: a X2 value of 25.9481 (p

What is the difference between percent and percent changes in index points?
Movements of an index from one month to another are usually expressed as percent changes rather than as changes in index points, because index point changes are affected by the level of the index in relation to its base period, while percent changes are not.

Can a ratio map be based on a percent of total?
While the construction of a ratio map based on the percent of total is fairly difficult to misapply (however creating one around a median, average, or statistical value would not be appropriate), the application of one attribute’s values against another’s is ripe with possibilities for erroneous associations.

Normalizing data factors out the size of areas by transforming counts (measures of magnitude) into ratios (measures of intensity). Ratio maps can be quickly designed in ArcMap. To normalize data in ArcMap, select a field to map (numerator) and a field to standardize against (denominator).

You are creating a proportion (percentage) by having ArcView perform simple division. In ArcMap two ways you can normalize an attribute include: By the sum total of the attribute’s values, turning the resulting ratio values into a percent of the total.

One obvious method for making the tests comparable is to convert the raw scores to percentages. We can easily do this by dividing each value by the total score for the test (40 and 60 for test1 and test2, respectively) and then multiplying this ratio by 100.
