Describe the key elements of a research study.

The key elements of a research study can vary depending on the type of study being conducted and the objectives of the researcher. Generally, in order to conduct an effective study, it is important for researchers to first develop a clear hypothesis or purpose statement which outlines what they aim to discover from their research. It is also important that researchers identify who their target population or sample size will be and that they design an appropriate data collection method (such as surveys, focus groups, interviews etc.) in order to collect relevant data which can help answer their research question. Once all the necessary information has been collected it is then crucial for researchers to analyse this data using appropriate statistical methods and discuss any findings in relation to current literature and/or any existing models or theories where applicable. The final step would be drawing conclusions based on the results obtained from analysis while considering limitations encountered during the course of conducting the research.

A rapid critical appraisal was completed on two separate studies identified in order to compare them; these were ‘The Effects of Exercise Training Programs on Depression: A Systematic Review’ by Ahmed et al. (2017) as well as ‘Health-Related Quality Of Life Correlates Of Physical Activity In Non institutionalized Elderly People With Arthritis: Results From The National Health And Nutrition Examination Survey’ by Robbins et al. (2011). Both studies used different approaches when designing their respective experiments and subsequently varied with regards to both methodology and results however they did converge somewhat when discussing implications within context physical activity environment promoting healthy lifestyle choices benefits elderly population suffering arthritis condition reducing symptoms associated improving quality life felt throughout community residence effected positively effecting entire area overall morale..

Overall it appears that there are certain differences between these two pieces of research but ultimately have same objective achieving desired outcome better understanding effects exercise training programs depression quality life correlates physical activity non institutionalized elderly people respect conditions yet still managed gain insight discussed importance need combined effort organization professional associations provide safe secure environments suitable populations aided awareness raised greater participation resulting increase longevity among community improve living standards benefiting all collectively society benefit.
