In recent years the idea of brain training has become quite popular; a quick Google search warrants almost 10 million results. Brain training is the concept that individuals can exercise their brains to improve aspects such as cognition, memory, and reflex. In a similar fashion to how quick this gained popularity, people began to question its legitimacy. After reviewing the available research, it is safe to say that brain training has a positive impact on older adults and their cognition. In…

Hypotheses The hand capturing method allows more accuracy when looking at our datum for the mean of body lengths of the Corophium Volutator. While using this method we are sampling from a wider surface at low tide, which allows us to pick out more of a variety of these organisms from the environment we are studying. As well as the Corophium Volutators otherwise known as mud shrimps have not been exposed to anything in this sampling technique therefore they are in their most natural habitat,…

3.2 Sampling I found my research participants through snowball sampling. Snowball sampling is a well established practice of asking respondents to recommend other possible research participants. Which in my case, the respondents willingly helped to share my survey link. The big advantage of this method is that it increases the number of respondents because people become more positive towards a researcher and are more willing to cooperate when introduced to someone they know. With snowball…

“Good design goes to heaven. Bad design goes everywhere.” – Mieke Gerritzen. This quote beautifully captures just how difficult it can be to create a solid research study. There are an incredible amount of things to consider when crafting a strong design and when it is done well there are numerous benefits. However, when it is does not go according to plan the intended outcomes crumble like a house of cards. The research study Predicting Adjustment During the Transition to College, had many…

in which is when there is trying to undertake the knowledge of knowing a cause-and-effect relationship. The best thing for each of these kind of data collections would be how important randomization techniques are, because each test needs a sample size of a population…

In the first article, The Relation Between Insecure Attachment and Post traumatic Stress: Early Life Versus Adulthood Traumas (Ogle & Rubin, 2015), probability sampling was used, with a population pool drawn from the “13th Wave” of the University of North Carolina Alumni (1964 - 1966) Heart Study, an ongoing longitudinal study of University of North Carolina students and their spouses (Sieger et al, 1992) including a total of 1598 participants. A convenience sampling of USC alumni would…
