DEFINITION of 'Analysis Of Variance-ANOVA'. A statistical analysis tool that separates the total variability found within a data set into two components: random and systematic factors. The random factors do not have any statistical influence on the given data set, while the systematic factors do.
A negative result from a home pregnancy test means you're unlikely to be pregnant. But sometimes it means you've taken the pregnancy test too early to know for sure. Wait until a day or two after your missed period and take another test to be sure. Women sometimes find the results of pregnancy tests hard to read.
