Chlamydia screening for all females in juvenile detention amenities is suggested at the Centers for Disease Control and Prevention (Torrone et al., 2015). Recognizing common factors of chlamydia could allow only specific screenings which would then reduce costs while still revealing many infections (Torrone et al. 2015). The study used various factors to classify features affiliated with chlamydia among females aged 12 to 18 years old in a juvenile detention facility in San Diego during January…

have been in use for quite some time, while technology has created a newer data collection method. Depending on the sample size and research strategy, each method has advantages and disadvantages that researchers must consider when designing the data collection method. Paper. Efficient and effective, paper-based surveys can quickly achieve wide-distribution to gain a broader sample. Paper-based surveys involve using pen and paper to collect data and optical scanning to record results…

McMahon Group examined six focus groups at the country club comprised of 43 members (69%), 12 employees (19%), and 7 non-members (11%). The under 46 age group members and non-members preferred full service over a golf only format. Furthermore, the focus groups revealed members felt the current level of service was not on par as expected from a private country club. Staff members expressed frustration with service limitations due to the board’s restrictions to maintain profitability. The…

the reduction in time and a number of samples translates directly to the costs (Ahuja et al., 2015). Expected Outcomes objective Expected project research outcome Data collection and spatial distribution - Intensities of the pest on lower, middle and upper leaves of the plant at different plant stages in three provinces for two seasons/ years. - The spatial distribution of the pest in the field at different plant stages. Sample unit The most efficient sample unit for the pest at different…

Significance The research problem discussed in the paper is the scarcity of organ donations worldwide. The literature examined some variables that affect signing an organ donor card. Some of the variables that the researcher identified that may affect SODC are: spirituality, purpose in life and attitudes toward donation as some factors that affect the signing of donor card. This research affects nursing practice by bringing awareness to a solvable problem, which is the scarcity of organ…

The sample size was large and for that reason intends for better outcome. Though using power calculation would have facilitated the researcher to gain an approximate sample size needed to recognize some significant difference among the variables. The sample was sufficiently chosen to get representativeness as the researcher chose nurses in different care settings while their main focus was in acute settings. By Choosing a smaller sample affects the results to be excessively…

Darrell Huff masterfully writes How to Lie With Statistics which covers many of the statistic gathering and displaying methods used today, from carefully picked averages to well chosen samples. He does not simply discuss these methods, however. He spectacularly demonstrates how companies, colleges, and quite often media sources use these tools to manipulate data into their favor. While it may appear to be fairly outdated to the casual reader, Darrell Huff's book still applies today, over…

There are different types of parametric tests to determine if a statistically significant difference is present. An independent-samples t-test is used when comparing two groups on one continuous dependent variable that is normally distributed. A paired-samples t-test is used when you look at the differences of one group across two time periods or observation periods. ANOVA tests are used when we are examining more than two groups or more than two observation periods. Slide 3: Our null…

“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…

get the leaf classification, one that was Random Forest, the other being Naïve Bayes and the third being Keras which is also known as Neural Networks. There have been many other cases like ours that have used Random Forest. Nantian Huang, Guobo Lu and Dianguo Xu have been one of the many who have used Random Forest and succeeded. In their paper, “A permutation importance based feature selection method for short term electricity load forecasting using Random Forest,” they talk about how they got…
