Distinguish between clinical significance and statistical significance as it relates to health care practices?

If medicine were purely a science-based profession, there would be no difference between the two: all significant phenomena would be so because they were proven significant through the scientific method. But medical decisions are often based on non-scientific criteria, and despite that, are often observed to work out for the patients' welfare.

How can this be? This simple answer is that health practitioners (in this context, nurses and physicians primarily) are called upon to take care of people even when lacking information upon which to make a scientifically-informed decision. Sometimes the decision is based on experience accumulated by the profession, but not yet verified scientifically; sometimes the decision is based upon the practitioners own experience and intuition.

We would all prefer that clinical decisions always have a firm scientific foundation, but as a matter of practice, this is not possible today. The gap between what scientists know and what medics must do is narrowing, but it is still wide. Modern society attempts to compensate for this by imposing rather strict standards upon health practitioners. The health professions themselves impose time-tested algorithms and procedures that have been shown to assist in caring for patients, even when science has not defined specific treatments or responses.

What are the combinations for a six digit code?

There are 1,000,000 ways of writing out a six digit number, if you are starting with 000000 and ending with 999999.

You are taking the number of possible numbers in the first position (10) and multiplying it by the number of possible numbers in the second position (again, 10), and continuing on till the sixth position. In other words, 10 to the sixth. With 10 representing the number of possible numbers (0 through 9) and six being the number of digits in number code.

If it is an alphanumeric code, then you would take the 26 letters plus the 10 numbers to get 36, and take that to the 6th power. Substantially greater.

How do you calculate coefficient of variation?

The coefficient of variation is calculated by dividing the standard deviation of a dataset by the mean of the same dataset, and then multiplying the result by 100 to express it as a percentage. It is a measure of relative variability and is used to compare the dispersion of data sets with different units or scales.

What is the Use of distribution transformer?

A transmission transformer steps the voltage up to a very high value so electricity can travel long distances on transmission lines from the power plant to a city or area with low loss.

A distribution transformer steps the high voltage back down to a level that can be used for local distribution and use by businesses and homes.

How many times does head and A tail if you flip a coin?

This is a Probability question

P(head) = 1/2 = 0.5

P(tail) = 1/2 = 0.5

Reason . when flippimng a coin it can only come down on one of two sides, viz, the head side or the tail side.

Difference between regression coefficient and correlation coefficient?

difference between correlation and regression?

(1) The correlation answers the STRENGTH of linear association between paired variables, say X and Y. On the other hand, the regression tells us the FORM of linear association that best predicts Y from the values of X.

(2a) Correlation is calculated whenever:

* both X and Y is measured in each subject and quantify how much they are linearly associated.

* in particular the Pearson's product moment correlation coefficient is used when the assumption of both X and Y are sampled from normally-distributed populations are satisfied

* or the Spearman's moment order correlation coefficient is used if the assumption of normality is not satisfied.

* correlation is not used when the variables are manipulated, for example, in experiments.

(2b) Linear regression is used whenever:

* at least one of the independent variables (Xi's) is to predict the dependent variable Y. Note: Some of the Xi's are dummy variables, i.e. Xi = 0 or 1, which are used to code some nominal variables.

* if one manipulates the X variable, e.g. in an experiment.

(3) Linear regression are not symmetric in terms of X and Y. That is interchanging X and Y will give a different regression model (i.e. X in terms of Y) against the original Y in terms of X.

On the other hand, if you interchange variables X and Y in the calculation of correlation coefficient you will get the same value of this correlation coefficient.

(4) The "best" linear regression model is obtained by selecting the variables (X's) with at least strong correlation to Y, i.e. >= 0.80 or <= -0.80

(5) The same underlying distribution is assumed for all variables in linear regression. Thus, linear regression will underestimate the correlation of the independent and dependent when they (X's and Y) come from different underlying distributions.

How is statistical data such as census numbers useful to geographers?

Statistical data such as census numbers provide geographers with valuable information about population distribution, demographics, and trends. This data helps geographers analyze patterns, make predictions, and understand the spatial relationships between people and the environment. It also helps them identify areas for further research and inform decision-making in urban planning, resource management, and other geographic studies.

What is meant by quantitative transfer?

Quantitative Transfer simply means that all the material to be transfered from one place to another must make the trip. For example, every particle of solid must be transferred from the weighing paper to the (clean) beaker.http://www.dartmouth.edu/~chemlab/techniques/q_transfer.html

What can be scattered?

Rain showers can be scattered, you will often hear the weather forcaster, forcasting scattered showers, seeds too can be scattered either by natural events such a being scattered by the wind, or animals, or a farmer may scatter seeds in order to grow crops. In maths terms you can produce scatter graphs with data plotted or scattered all over the graph area.The final answer is to have your ashes scattered.

What is the nature of hypothesis testing?

A hypothesis must be subjected to rigorous testing before it becomes a theory. A hypothesis is used to explain some phenomenon about the natural world. Once a hypothesis has been created, it can be used to formulate predictions. These predictions in turn are then tested to be accurate through experimentation or observation.

What is Slovin's formula?

Slovin's formula is a mathematical formula used to determine the sample size needed for a survey or study. It takes into account the population size, desired level of confidence, and margin of error to calculate the appropriate sample size for a given study. It is commonly used in statistics and research to ensure accurate and reliable results.

What are 3 examples of discrete variation in humans?

From a purist point of view, there is probably only a few true examples of discrete variation in humans. However, we have the common sense practical real world ways to describe some things as discrete. A coma scale used, Glasgow, is discrete. Also, vision is expressed as discrete values. See attached related links. In addition, number of seizures is discrete along with pulse (heart) rate.

What is measuring or measurements?

Measuring or measurement refers to keeping track or recording of the values of variables at certain points in time.

A simple example would be:

When you are cooking meat, you might use a thermometer to keep track of the temperature of the meat as it cooks. Each time you test the temperature, you are measuring or taking a measurement.

How do you measure the level of interest?

The question is very broad. Obviously, if we are talking about the level of interest in a particular product, for example, a new movie, the level of interest is sales. If people are interested in higher education, then a measure of this can be enrollment. Attendence at an activity is another direct measure. Surveys are an additional means of measuring interest, but it can be difficult to assess. One can ask the questions, such as "Which subjects in school do you find most interesting?" or "Do you contribute to charitable organizations?" that will provide some measure of people's level of interest in certain areas. For example, if you found that many people contribute money to groups concerned with environmental issues, you could conclude that the level of interest is high for these causes.

What is the difference between control and experimental variables?

Control variables are kept constant throughout an experiment to ensure that any changes in the dependent variable are due to the manipulation of the independent variable. Experimental variables, on the other hand, are the factors that are deliberately changed by the researcher to observe their effect on the dependent variable.

What is a tabulation?

A tabulation is the process of organizing and presenting data in a structured format, typically using tables or charts to make it easier to understand and analyze. It involves summarizing and counting data to reveal patterns or relationships within the information.
