statistical treatment in research paper example

For a statistical treatment of data example, consider a medical study that is investigating the effect of a drug on the human population. As the drug can affect different people in different ways based on parameters such as gender, age and race, the researchers would want to group the data into different subgroups based on these parameters to ...

Table of contents. Step 1: Write your hypotheses and plan your research design. Step 2: Collect data from a sample. Step 3: Summarize your data with descriptive statistics. Step 4: Test hypotheses or make estimates with inferential statistics.

Research Paper Statistical Treatment of Data: A Primer. March 11, 2024. We can all agree that analyzing and presenting data effectively in a research paper is critical, yet often challenging. This primer on statistical treatment of data will equip you with the key concepts and procedures to accurately analyze and clearly convey research findings.

Categorical variables represent groupings of things (e.g. the different tree species in a forest). Types of categorical variables include: Ordinal: represent data with an order (e.g. rankings). Nominal: represent group names (e.g. brands or species names). Binary: represent data with a yes/no or 1/0 outcome (e.g. win or lose).

Introduction. Statistical analysis is necessary for any research project seeking to make quantitative conclusions. The following is a primer for research-based statistical analysis. It is intended to be a high-level overview of appropriate statistical testing, while not diving too deep into any specific methodology.

The term "statistical treatment" is a catch all term which means to apply any statistical method to your data. Treatments are divided into two groups: descriptive statistics, which summarize your data as a graph or summary statistic and inferential statistics, which make predictions and test hypotheses about your data. Treatments could include:

Example: Inferential statistics. You randomly select a sample of 11th graders in your state and collect data on their SAT scores and other characteristics. You can use inferential statistics to make estimates and test hypotheses about the whole population of 11th graders in the state based on your sample data.

In a previous article in this series, we looked at different types of data and ways to summarise them. 1 At the end of the research study, statistical analyses are performed to test the hypothesis and either prove or disprove it. The choice of statistical test needs to be carefully performed since the use of incorrect tests could lead to misleading conclusions.

Statistical methods involved in carrying out a study include planning, designing, collecting data, analysing, drawing meaningful interpretation and reporting of the research findings. The statistical analysis gives meaning to the meaningless numbers, thereby breathing life into a lifeless data. The results and inferences are precise only if ...

W. R. Leo. Statistics plays an essential part in all the sciences as it is the tool which allows the scientist to treat the uncertainties inherent in all measured data and to eventually draw conclusions from the results. For the experimentalist, it is also a design and planning tool.

Now, if we divide the frequency with which a given mean was obtained by the total number of sample means (36), we obtain the probability of selecting that mean (last column in Table 10.5). Thus, eight different samples of n = 2 would yield a mean equal to 3.0. The probability of selecting that mean is 8/36 = 0.222.

CHAPTER III METHODOLOGY. This chapter reveals the methods of research to be employed by the researcher in conducting the study which includes the research design, population of the study, research instrument and its development establishing its validity and reliability, data gathering procedures, and the appropriate statistical treatment of data

Type and distribution of the data used. For the same objective, selection of the statistical test is varying as per data types. For the nominal, ordinal, discrete data, we use nonparametric methods while for continuous data, parametric methods as well as nonparametric methods are used.[] For example, in the regression analysis, when our outcome variable is categorical, logistic regression ...

1 Introduction. Statistics is a set of methods used to analyze data. The statistic is present in all areas of science involving the. collection, handling and sorting of data, given the insight of ...

The p value determines statistical significance. An extremely low p value indicates high statistical significance, while a high p value means low or no statistical significance. Example: Hypothesis testing. To test your hypothesis, you first collect data from two groups. The experimental group actively smiles, while the control group does not.

For example, in a survey regarding the election of a Mayor, parameters like age, gender, occupation, etc. would be important in influencing the person's decision to vote for a particular candidate. Therefore the data needs to be treated in these reference frames. An important aspect of statistical treatment of data is the handling of errors.

A good research design provides information concerning with the selection of the sample population treatments and controls to be imposed and research work cannot be undertaken without sampling. Collecting the data and create data structure as organizing the data, analyzing the data help of different statistical method, summarizing the analysis ...

Types of descriptive statistics. There are 3 main types of descriptive statistics: The distribution concerns the frequency of each value. The central tendency concerns the averages of the values. The variability or dispersion concerns how spread out the values are. You can apply these to assess only one variable at a time, in univariate ...
