HCS/438 DQ’s
Week 1:
DQ1: What are the differences between descriptive and inferential statistics? According to Bennett (2009), the biggest difference between descriptive and inferential statistics is that descriptive statistics "deals with describing raw data in the form of graphics and sample of statistics" and inferential statistics "deals with estimating population parameters from sample data." This means that inferential statistics would be an estimate because the data would be estimated from sample data rather than using specific data whereas descriptive statistics would be more accurate. An example of descriptive statistics would be trying to find an average of something such as a G.P.A. or your overall grade in a class. Inferential statics can be used to find the effectiveness of a new medication on a target group.

DQ2: What are the four levels of management?
The four levels of management are:
The nominal level of measurement is the simplest level of variables such as hair color or gender. Ordinal level of measurement is data with a ranking or ordering scheme such as a star rating used on movies. Interval level of measurement is when intervals are meaningful but ratios are not such as Fahrenheit temperatures. Ratio level of measurement is when intervals and ratios are both meaningful such as data consisting of distances. Data is classified into four levels of measurement so the information is easy to follow and research. The measurements help researchers keep data organized, this also helps to keep the measurements accurate. EBOOK COLLECTION: Bennett, J.O., Briggs, W.L., & Triola, M.F. (2009).

T F 1. The probability that X takes on a value that is between 3 and inclusive of 4 can be written as P(3 < X ( 4).
T F 2. P(X > x ) + P(X < x) + P(X = x) = 1.
T F 3. If P(X > x) = 0.34 and P(X = x) = 0.10, then P(X ( x) = 0.56.

...As we analyze the factors contributing to health care costs we must find a solution that provides high-quality care for an aging population. Improvements to modern medicine are prolonging life causing a schism between a health care system oriented towards acute care and the increasing chronic care needs of older adults. Studies do show that health care costs for older Americans account for one third of all national health care expenditures. This being said the average expenditure for health...

...What are some communicable diseases or threats currently affecting public and community health in your area?
