However, some are more successful than others, for example at the top of the evidence hierarchy for quantitative research design is Systematic Reviews, this is when a document is written by a group of people and they summarise their findings after looking at all the relevant documents relating to their question, it is also seen as the least biased. On the other hand, at the bottom of the hierarchy is ideas and opinions, these are less likely to be used as they are not based on fact and have no scientific evidence to support them. One of the journal articles “Effects of Relaxation and Guided Imagery on Knee Strength, Reinjury Anxiety, and Pain Following Anterior Cruciate Ligament Reconstruction” (Cupal and Brewer, 2001, p.1) uses quantitative data. Quantitative research is the “use of numerical measurement and analysis which can then be statistically analysed to determine whether a relationship existed between the two” (Gratton & Jones, 2004, p.21). The advantages of using quantitative data are that it is relevant to the subjective population as it aims to focus on athletes that have the same injury of anterior cruciate ligament (ACL) and all of the participants are at the same stage of their injury. Also, the data that they use is very precise and accurate making it more reliable and thus can be trusted by others. Nevertheless, there …show more content…
All three of the authors agreed that there were significant changes in the anxiety of the injured players even though they had all used different methods they still come up with the same conclusion; however, some were more reliable and had more depth. The trade journal Sportex didn’t really have much of a connection, and wasn’t relevant to the topic as the author never answered the question he started with. The research in this topic could be improved if there was more of a balanced argument within the sources, this could be achieved if they wrote about some of the negatives and not just the positives. This would then make it easier for us as a field of practice to differentiate between the good research methods and the great research methods. The overall conclusion that can be determined about this essay question of the importance of scientific research and evidence based practice, is that the subject on whom all four authors discuss is broad and can be understood in many different ways by different researchers consequently, giving us as a field of practice, other ways to develop our knowledge and
