Please suggest the answer by keeping research methodologies concept in mind.
A scientist has two kymographs and wants to figure out which one will produce a consistent dose-response relation for a 10mg dose of acetylcholine on the chick ileum tissue. The response is the expansion of the tissue that is recorded as the height moved by the stylus on the sheet placed on the kymograph drum. Following are the results recorded by the sheet:
Instrument A in cm | Instrument B in cm |
6.5cm | 7.1cm |
6.8cm | 7.0cm |
7.1cm | 4.8cm |
6.9cm | 4.9cm |
7.2cm | 6.7cm |
6.5cm | 6.7cm |
6.6cm | 6.9cm |
7.1cm | 6.9cm |
7.1cm | 6.8cm |
6.5cm | 6.5cm |
The correct dose response for a 10mg dose of acetylcholine is 6.5cm. Which instrument should the scientist select and why?
