Examples use in sentences:

A common mistake is confusing incidence with incident. While incidence refers to the rate or frequency of occurrence, an incident is a single event or occurrence.
For example, you might say The incidence of car thefts has increased, but A car theft is an unfortunate incident.
Another error is using incidence when prevalence is more appropriate. Incidence typically refers to new cases over a period, while prevalence refers to all existing cases at a given time.
To master this word for your SAT, remember its connection to frequency and rate of occurrence. Whether you’re discussing scientific studies, statistical analyses, or everyday events, understanding and correctly using incidence will enhance your vocabulary and comprehension skills.
