Random variable

than for the depth of its data. 2. Longitudinal is a major disadvantage of this design is the length of time needed for data collection. 3. Correlational is the main question is whether or not variables co-vary. 4. Ex- post facto words mean “after the fact”. 5. Cross -sectional eliminates the confounding variable of maturation. 6. Correlational quantifies the magnitude and direction of a relationship. 7. Longitudinal collects data from the same group at several points in time. 8. Survey can be…

exchange rate, treasuries yield, and volatility index toward Gold return. The model that will be used under APT was the multi factor model as below where the return of gold were linear combination with those factors and risk free rate of return. The random error term in the equation were not related with the risk…

The researcher will then ask the random respondents for consent and approval to answer the psychological tests until the desired number is reached. In addition, the researcher will maintain confidentiality among the respondents and personal identifiable information such as name, social security number, date and place of birth should not be collected. Materials In this research study, two psychological instruments are going to be used to measure the variables depression, anxiety, stress and…

in the post-test, with a longer reaction time in the odd one out task, indicating that after exposure to food stimuli these individuals attention was impaired. Method There will be two levels of the independent variable in order to test this hypothesis. The first independent variable will be either high/low preference of fatty foods. This will be conducted through a pre-post test questionnaire. The questionnaire will…

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…

milk and better development. In the article I read, the researchers did an exceptional job on perfecting their experiment. They had both dependent and independent variables, and an experimental group and a control group. Lucas and Morley also kept in mind the confounding variables, and incorporated those with their findings. By using random assignment, they choose…

There is currently a nurse shortage that is increasing in intensity every year and as stated by the U.S. Department of Health and Human Services Health Resources and Services Administration, by the year 2025 Arizona is estimated to have the greatest shortage of nurses. This shortage could be the result of a high turnover among nurses as a result of burnout. The nursing shortage forces nurses to increase their workload, meaning their patient to nurse ratio. With an increase in workload more…

because it is the most well-known design connects, with social sciences. Moreover, this design is often to acknowledge with survey research, a method of data collected often by many social science fields. Moreover, the survey that researcher asks random questions from a person so that the person; response to set of questions about his or her background, past knowledge, and behavior. Therefore, some studies that researcher worry about the establishing of causal relations, the research try to…
