Question 1

Why BACIPS design is necessary for my research

Answer 1

BACIPS allows for assessment of treatment effect size in cases where a treatment is not replicated spatially or where random assignment of sites is not possible.

Question 2

What is the parameter of interest within a BACIPS design?

Answer 2

The estimated difference in the response variable between Control and Impact sites on each sampling date.

Question 3

What does the difference between the Control & Impact site during the before period capture?

Answer 3

spatial variation; provides an estimate of the expected difference between the two sites in the After period if no intervention occurred

Question 4

What assumptions are made by the BACIPS approach?

Answer 4

that without restoration (or other more general intervention), the difference between the means of the impact and control sites would be constant over time
