One of the main reasons for this struggle is they try to memorize. But when the problem changes, so do the steps, and students are left confused. The key to success in algebra is to understand why youre doing each step. Or in other words, its not just about the x, but about the why. We know what youre thinking: if only it were easy […]

For this summers project we are going to use data from the General Social Survey (GSS). The GSS is a sociological survey created and regularly collected since 1972 by the National Opinion Research Center at the University of Chicago. It is funded by the National Science Foundation. The GSS collects information and keeps a historical record of the concerns, experiences, attitudes, and practices of residents […]
This concept has been a difficult one for me to grasp but this is my take on the subject. I currently work on a post orthopedic surgery/trauma unit. On our unit, it is very important that all patients get out of bed at least once on the day of surgery (activity level allowing). According to Zou, et all: It was found that adding a 15-minute […]
For any distribution, there are an equal number of values above and below the mean. Do you agree? Coefficient of variation CV = SD /mean *100 = 10/40*100 = 25% Range by use of Thumb Range Rule = 4*SD =4*10=40 Can you explain these numbers? What do they mean? According to the Empirical rule, about 95% of the observations lie within plus and minus 2.00 […]

In the hypothetical case, A school district has analyzed data on student performance and noticed there are is a significant proportion of the student population with potential learning disabilities. To remedy the situation, the school district applied a range of interventions, including 1) systematic and explicit instruction, 2) visual representation of relationships and functions, 3) peer-assisted instruction and 4) ongoing formative assessment. However, the school […]
Discussion 6: Choosing the Correct Statistical Procedure!! Choosing the Correct Statistical Procedure!! Hi class. As promised, now that the semester is almost over, let’s decide which statistical procedure is most appropriate to answer your research questions.

Confidence Intervals In everyday terms, a confidence interval is the range of values around a sample statistic (such as mean or proportion) within which clinicians can expect to get the same results if they repeat the study protocol or intervention, including measuring the same outcomes the same ways. As you ask yourself, “Will I get the same results if I use this research?”, you must […]

Chapter 5: 1) A gambler claimed that he had loaded a die so that it would hardly ever come up 1. He said the outcomes of 1, 2, 3, 4, 5, 6 would have probabilities 1/20, 1/6, 1/6, 1/6, 1/6, 1/6 respectively. Can he do what he claimed? Why or why not? Is a probability distribution described by listing the outcomes along with their corresponding probabilities? […]

In public health, data are often gathered from separate groups in order to describe health-related behavior for a topic of interest. In practice, a larger sample is often surveyed, and then focus groups or interviews can be conducted with a smaller subset of the sample. The quantitative survey data from a larger group helps to identify health-related trends and patterns within the sample group. The […]
