What are impact studies? Impact studies are research efforts designed to evaluate the effects of a particular intervention, policy, or program. They aim to measure the changes brought about by these actions, whether positive or negative. Why are impact studies important? They provide valuable insights into the effectiveness of initiatives, helping policymakers, organizations, and stakeholders make informed decisions. By understanding what works and what doesn't, resources can be allocated more efficiently, ensuring better outcomes. How do impact studies work? They typically involve collecting data before and after an intervention, using various methods like surveys, interviews, and statistical analysis. This data helps to identify any significant changes and attribute them to the intervention. Who benefits from impact studies? Governments, non-profits, businesses, and communities all benefit from the knowledge gained, leading to improved strategies and better results.
What Are Impact Studies?
Impact studies analyze the effects of projects, policies, or programs on specific outcomes. They help understand what works, what doesn't, and why. Here are some fascinating facts about impact studies.
- 01
Impact studies often use control groups to compare results. This helps isolate the effect of the intervention from other factors.
- 02
Randomized Controlled Trials (RCTs) are the gold standard in impact studies. They randomly assign participants to either the intervention or control group.
- 03
Longitudinal studies track the same subjects over a long period. This helps see how impacts change over time.
- 04
Quasi-experimental designs are used when random assignment isn't possible. They use statistical methods to mimic randomization.
- 05
Mixed-methods combine quantitative and qualitative data. This provides a fuller picture of the impact.

Choose the sample. This involves deciding who will be included in the study.
- 15
Collect baseline data. This provides a point of comparison for measuring impact.
- 16
Implement the intervention. This is the program, policy, or project being studied.
- 17
Collect follow-up data. This measures the outcomes after the intervention.
- 18
Analyze the data. This involves statistical methods to determine the impact.
- 19
Report the findings. This includes writing a report and sharing the results with stakeholders.
