Statistical Statistics : Descriptive Statistics

If I was doing this study, my hypothesis would be that “people, who receive an aversive stimulus every time they give an incorrect answer, will try harder to get the correct answer than those who do not receive anything”. My independent variables, which are the variables that researcher manipulates, would be the electric shocks and the emotional motivation; and my dependent variable, which is the variable that is tested and measured, would be the members’ results.

Statistics provides us with very useful tools and techniques that aide us in dealing with real world scenarios. I have been able to learn several useful concepts by studying statistics that can aide me in making rational and informed decisions that are supported by the analysis results. Statistics as a discipline is the application and development of various processes put in place to gather, interpret, and analyse the information. The quantification of biological, social, and scientific phenomenons, design and analysis of experiments and surveys, and application of

There are several parts to the experiment such as both the independent and dependent variables. The independent variable is controlled or changed during the experiment to test the effects on the dependent variable. The dependent variable is tested and measured during the test .A controlled variable is an example for an independent variable would be variable that is held constant throughout the experiment. An example is a theory that could extend a person’s life expectancy. The independent variable is the amount of vitamin given to the subject within the experiment. The dependent variable is the life span

Dependent variables are ones that change due to the independent variable. Independent variables are variables that can be manipulated or measured. This influences the dependent variables.

Independent variableIdentify the independent variable (IV), which is the variable that you hypothesize will cause or influence the other variable. *

2) Isolation/causation. Isolation is if only thing changing is that which is being manipulated whether up or down, then the change in effect is caused by the change in IV (the thing manipulated). It is harder to get isolation from psychology, than that from physical experiments. In experiments, even in a double blind study, the IV and subjects are changing. This can prove to make things even more difficult when the DV is based on the subject, the change on the DV may be due to difference in samples and not on changes due to the IV. Where a confounding variable is the environment or situation, the difference in subjects such as age or gender is a subject variable. This is important to note the differences as subject difference Subject variables

Researchers or research teams who elect a quantitative study are going to determine the relationship between an independent variable and a dependent variable within a population (Babbie, E.R., 2010). There are two types of quantitative study designs: descriptive and experimental. A descriptive design typically measures the subject once and establishes the association between the independent and dependent variables (Mujis, D, 2010). An experimental design measures the subject before and after a treatment and establishes causality between the variables (Brians, C.L. et al, 2011).

Statistics are used in many different ways in my workplace. The use of statistics is for the improvement of quality care and safety. Statistics are also used to measure employee compliance in regards to hand washing and proper use of policies and procedures. We also use charts and graphs to show infection rates, skin integrity, falls within the facility, budget concerns, and many more. These graphs help hospital personal improve care and safety to provide quality care to all patients. Graphs can also be used to measure patient and employee satisfaction.

The research question, in this case, is “Are subjects less accurate in their hypnotic response reporting under more anonymous conditions” (Younger et al., 2005). Independent variables are the variables that stand alone, and it is not changed by the other variables one is measuring. On the other hand, dependent variable refers to the variable that changes because of variations in the independent variable. Therefore, the independent variable is less accurate subjects and anonymous conditions while the dependent variable is the hypotonic response reporting.

The independent variables are those that are changed throughout the experiment. In my experiment I am going to change the amount of egg white mixture on the ice cream (in my first experiment I put very little and the experiment didn’t work out). I will also be changing the type of ice cream. This will not affect the experiment but it will change the taste.

3) The performance of personal and business investments is measured as a percentage, return on investment. What

An independent variable is a variable that is manipulated and whose effect is being studied. The independent variable in this demonstration is the choices that each group had to pick from for their answer. A dependent variable is what changed due to the manipulation of the independent variable. The dependent variable in this demonstration was how the choices that each group had chose, or more specifically, how many people showed that they understood conservation and how many people did not.

Statistics is a mathematical science pertaining to the collection, analysis, interpretation or explanation, and presentation of data. It is applicable to a wide variety of academic disciplines, from the physical and social sciences to the humanities. Statistics are also used for making informed decisions – and misused for other reasons – in all areas of business and government. Statistical methods can be used to summarize or describe a collection of data; this is called descriptive statistics. In addition, patterns in the data may be modeled in a way that accounts for randomness and uncertainty in the observations, and then used to draw inferences about the process or population being studied; this is called inferential statistics. Both

Leah Henigan Carlo Statistics 15 May 2015 Statistics are used daily in a number of fields. Statistics can be defined as the practice of collecting, classifying, analyzing, and interpreting numerical data in large quantities to determine probability. Statistics are even used prominently in sports such as Major League Baseball. Sports analysts in major league baseball look at a number of statistics to make predictions and define strategies for their teams, so they an influence a favorable outcome.
