Tips for Data Use
Margins of error Period estimates Analyzing trend
Percentage change Index of change Adjusting for inflation
Understanding Margin of Error
Sampling error Arises when data are gathered from a
sample rather than the full population Margin of error (MOE)
A measure of sampling error Describes precision of an estimate at a
given confidence level MOEs should not be ignored
MOE Example
Understanding Period Estimates
Period estimate Describes average characteristics over a
time period of specified length Example: ACS estimates
Point-in-time estimate Captures conditions on the day of
measurement Example: Decennial Census
Period estimates more difficult for analyzing trends
Tips for Analyzing Trend
Percentage change (( New Number / Old Number ) – 1 ) * 100
Index of change Divide values for all years by beginning year
value, so first year = 100%
Inflation adjustment If working with dollar values, adjust for
inflation For help, try an online calculator BLS CPI Calculator (http://data.bls.gov/cgi-bin/cpicalc.pl)
