1. 1.

   Fictional fieldwork: infiltration times for a fixed water volume at five park sites are 20, 22, 25, 28, 55 seconds. Lower time means faster infiltration under this protocol. All readings are invented. Students used safe level ground but chose sites near a path for convenience; soil moisture was not recorded. Explain why fixed water volume is needed when comparing times.

   Fictional fieldwork: infiltration times for a fixed water volume at five park sites are 20, 22, 25, 28, 55 seconds. Lower time means faster infiltration under this protocol. All readings are invented. Students used safe level ground but chose sites near a path for convenience; soil moisture was not recorded. Calculate the median and range of infiltration times.

   Fictional fieldwork: infiltration times for a fixed water volume at five park sites are 20, 22, 25, 28, 55 seconds. Lower time means faster infiltration under this protocol. All readings are invented. Students used safe level ground but chose sites near a path for convenience; soil moisture was not recorded. Explain how path-side convenience sampling may bias the result.

4. 4.

   Fictional fieldwork: infiltration times for a fixed water volume at five park sites are 20, 22, 25, 28, 55 seconds. Lower time means faster infiltration under this protocol. All readings are invented. Students used safe level ground but chose sites near a path for convenience; soil moisture was not recorded. Explain how to investigate the 55-second reading without simply deleting it.

5. 5.

   Fictional fieldwork: infiltration times for a fixed water volume at five park sites are 20, 22, 25, 28, 55 seconds. Lower time means faster infiltration under this protocol. All readings are invented. Students used safe level ground but chose sites near a path for convenience; soil moisture was not recorded. Design a stronger test of whether trampling slows infiltration.

6. 6.

   Fictional fieldwork: infiltration times for a fixed water volume at five park sites are 20, 22, 25, 28, 55 seconds. Lower time means faster infiltration under this protocol. All readings are invented. Students used safe level ground but chose sites near a path for convenience; soil moisture was not recorded. Assess whether these five readings justify a park-wide drainage intervention.
