Research bias is one of the threats to validity in qualitative research. Research bias occurs because researchers bring into studies their own personal beliefs‚ values‚ experiences‚ and bias. Research bias is considered a threat due to an error being introduced into sampling or testing by selecting or encouraging one outcome or answer over others (Pannucci & Wilkins‚ 2010‚ p. 619). Researchers are prone to human error and therefore they make mistakes and get things wrong (Norris‚ 1997). To minimize

Randomized controlled trials (RCTs) are considered as the best research design for decisions about the effect of different interventions but randomization does not apply to many clinical issues related to real world setting. The current scenario of clinical research indicates some major challenges associated with traditional clinical trials and patient care. The foremost challenges being most researchers consider RCTs as the mainstay of clinical research‚ which instead are slow and expensive. They

Your task is to determine which of the three major causal models (i.e.‚ interpretations) could account for each finding. Indicate in the table below‚ by placing an X in the appropriate space‚ which of these three models could provide a possible explanation. Place an X in the space only if you judge the causal model to be possible & reasonably plausible. If you decide that the third model is possible‚ generate two possibilities for what variable “C” could represent‚ and type a short summary

Controlled Assessment Task: State the hypothesis you will be testing in your investigation: The speed of a metal carbonate breaking down depends on where the metal is in the reactivity series. The more reactive a metal is the slower it takes for it to breakdown. The less reactive a metal is it breaks down faster. Explain the hypothesis using scientific ideas: The metal carbonate which is lower in the reactivity series such as copper can thermally decompose much faster because it is
