An intervening variable is a variable that affects the relationship between an independent variable and a dependent variable.. Often this type of variable can appear when researchers are studying the relationship between two variables and don't realize that another variable is actually intervening in the relationship.. Intervening variables pop up in many different research situations.

The Unit 8 discussion board wraps up topics that were covered throughout the course in addressing and testing criminal justice research hypothesis and null hypotheses. Cohort studies follow individuals or specific cohorts as they change over time. staying current in a single primary area is oftentimes difficult. Research factors/variables must be clearly defined. many variables that mold the crime in a particular town, city, county, state, region, or other jurisdiction. It is a variable that stands alone and isn't changed by the other variables you are trying to measure.
