PLEASE EXPLAIN HOW TO COMPLETE THE DEFINITION OF IV & DV FOR EACH QUESTION...                                                                                                                                                                                            Operational Definitions, IVs, DVs, & Hypotheses Directions: Identify the independent variable (IV) and the dependent variable (DV) for each of the research scenarios and given the operational definitions for each. Additionally, provide a hypothesis for each research scenario. 1. A nurse researcher is interested in how the activity level of four year olds is affected by viewing a 30 minute video of Spongebob Squarepants or a 30 minute video of Sid the Science Kid. IV: ________________________________________________________________________________ Operational definition of IV: ___________________________________________________________ DV: _______________________________________________________________________________ Operational definition of DV: ___________________________________________________________ Hypothesis: _________________________________________________________________________ 2. A nurse researcher wants to test the impact of a new drug designed to increase the ability of teenagers with ADHD to take accurate notes in class. IV: ________________________________________________________________________________ Operational definition of IV: ___________________________________________________________ DV: _______________________________________________________________________________ Operational definition of DV: ___________________________________________________________ Hypothesis: _________________________________________________________________________ 3. A nurse researcher believes that cooling the temperature of a patient’s room may have an impact on recovery time. IV: ________________________________________________________________________________ Operational definition of IV: ___________________________________________________________ DV: _______________________________________________________________________________ Operational definition of DV: ___________________________________________________________ Hypothesis: _________________________________________________________________________ Expert Answer Anonymous answered this Was this answer helpful? 0 0 278 answers 1. Independent variable (IV) is the four year kid watching videos, Dependent variable is (DV) is level and the hypothesis is childrens activity level can be increase by watching different videos. 2. IV : new drug, DV: accurate notes takes in class and the hypothesis is teenager tested with drug can show its impact on function. 3. IV : temperature and DV is recovery time and the hypothesis is patients can easily recoverd when low temperature how would you answer the operational def. how would you answer the operational definition for IV & DV

Explanation / Answer

Operational definition is specified by mentioning the type of variable.
1. Independent variable (IV) is the type of video watched. IV is categorical (nominal) variable with 2 categories (Spongebob video and Sid science video).
Dependent variable is (DV) is the activity level. DV is a continuous (ratio type) variable;
Hypothesis is children’s activity level remains the same by watching different videos or not.

2. IV : impact of new drug(Continuous : Ratio type)
  DV: ability of taking accurate notes takes in class (Continuous : Interval type)
Hypothesis is teenager tested with drug has no change in ability to take accurate notes in class or has increased.

3. IV : temperature( Continuous : Interval type)
DV is recovery time ( Continuous : Ratio type)
Hypothesis is temperature change has any impact on recovery time or not.
