[MetaROR] Ch6 Execution of Replications — author revisions

[LukasWallrich]

Author revisions for Chapter 6 (Execution of Replications) from the MetaROR reviews (R1, R2, R3).

• Section 6.2.1 (Small Telescope): Rewrite the explanation for clarity — the "rule of thumb" from Simonsohn (2015) is currently insufficiently explained. (R1) (in Ch6 revisions: Small Telescopes clarity, OSC link, Piloting, framework tie-in (#19) #40)
• Section 6.2.1: Link the Small Telescope approach to the Open Science Collaboration (2015) reproducibility study. (R2) (in Ch6 revisions: Small Telescopes clarity, OSC link, Piloting, framework tie-in (#19) #40)
• Section 6.3: Tie changes in methods back to deductive/inductive reasoning and underlying theory. (R1) — coordinate with the framework-integration task in Cross-cutting editorial changes. (in Ch6 revisions: Small Telescopes clarity, OSC link, Piloting, framework tie-in (#19) #40)
• Section 6.4 (Piloting): Rewrite to better link the two paragraphs. (R1) (in Ch6 revisions: Small Telescopes clarity, OSC link, Piloting, framework tie-in (#19) #40)
• Section 6.1: Review for replication-specific content — much of it is general preregistration advice that may already be familiar to the target audience. (R3) (in Ch6 revisions: Small Telescopes clarity, OSC link, Piloting, framework tie-in (#19) #40)
