For each hypothesis listed, identify the Independent Variable (IV). Indicate if the IV is continuous or categorical. If the IV is continuous, indicate if it is on a Ratio or Interval Scale. Then, identify the Dependent Variable (DV) . Indicate if the DV is continuous or categorical. If the DV is continuous, indicate if it uses a ratio or interval scale. If the DV is categorical indicated if it is uses a nominal or ordinal scale.
