What is the statistical analysisStatistical analysis is fundamental to all experiments that use statistics as a research methodology. Most experiments in social sciences and many important experiments in natural science and engineering need statistical analysis. Also called: statistical process control The control chart is a graph used to study how a process changes over time. A control chart always has a central line for the average, an upper line for the upper control limit and a lower line for the lower control limit. By comparing current data to these lines, you can draw conclusions about whether the process variation is consistent (in control) or is unpredictable (out of control, affected by special causes of variation). Control charts for variable data are used in pairs. The top chart monitors the average, or the centering of the distribution of data from the process. The bottom chart monitors the range, or the width of the distribution. If your data were shots in target practice, the average is where the shots are clustering, and the range is how tightly they are clustered. Next

Such a model tries to explain, or predict, the variations in the Y-variable(s) from the variations in the X-variable(s). The link between X and Y is achieved through a common set of samples for which both X- and Y-values have been collected. The X- and Y-variables can be denoted with a variety of terms, according to the particular context (or culture). The most common ones are listed in the table below: Usual names for X- and Y-variables takes into account several predictive variables simultaneously, thus modeling the property of interest with more accuracy. Building a regression model involves collecting predictor and response values for common samples, and then fitting a predefined mathematical relationship to the collected data. Next

Statistical learning is the ability for humans and other animals to extract statistical regularities from the world around them to learn about the environment. Although statistical learning is now thought to be a generalized learning mechanism, the phenomenon was first identified in human infant language acquisition. The earliest evidence for these statistics learning abilities comes from a study by Jenny Saffran, Richard Aslin, and Elissa Newport, in which 8-month-old infants were presented with nonsense streams of monotone speech. Each stream was composed of four three-syllable “pseudowords” that were repeated randomly. After exposure to the speech streams for two minutes, infants reacted differently to hearing “pseudowords” as opposed to “nonwords” from the speech stream, where nonwords were composed of the same syllables that the infants had been exposed to, but in a different order.

Gathered data is frequently not in a numerical form allowing immediate appliance of the quantitative mathematical-statistical methods. In this paper are some basic aspects examining how quantitative-based statistical methodology can be utilized in the analysis of qualitative data sets. The transformation of qualitative data into numeric values is considered as the entrance point to quantitative analysis. Concurrently related publications and impacts of scale transformations are discussed. Subsequently, it is shown how correlation coefficients are usable in conjunction with data aggregation constrains to construct relationship modelling matrices. For illustration, a case study is referenced at which ordinal type ordered qualitative survey answers are allocated to process defining procedures as aggregation levels. Finally options about measuring the adherence of the gathered empirical data to such kind of derived aggregation models are introduced and a statistically based reliability check approach to evaluate the reliability of the chosen model specification is outlined.

When discussing single numbers, a random number is one that is drawn from a set of possible values, each of which is equally probable. This page describes the statistical analyses that have been conducted of the service. Before we try, let's define what exactly we mean by a random number. ORG is a true random number service that generates randomness via atmospheric noise. In statistics, this is called a uniform distribution, because the distribution of probabilities for each number is uniform (i.e., the same) across the range of possible values. For example, a good (unloaded) die has the probability 1/6 of rolling a one, 1/6 of rolling a two and so on. Next

But we cannot begin to interpret that data until we establish a context into which it can be placed. For this reason, statistical analysis is one of a researcher’s most valuable approaches to analyzing data. Statistical analysis is used to analyze and interpret numerical or categorical data. There are two basic functions for which biological statistical analysis, or “biostatistics,” is used in the health sciences: Presenting and interpreting data in a manner that shows statistical validity is a vital part of this process. Understanding the P-Value One of the most recognized ways to evaluate biostatistics is to look at the p-value of a test. P-value measures the difference between the baseline, or null, hypothesis and the alternative hypothesis being tested. The p-value allows us to determine whether we should accept or reject the null hypothesis. Next

More probability density is found as one gets closer to the expected (mean) value in a normal distribution. Statistics used in standardized testing assessment are shown. The scales include standard deviations, cumulative percentages, Z-scores, and T-scores. Statistics is a branch of mathematics dealing with the collection, classification, analysis, interpretation of numerical facts, for drawing inferences on the basis of their quantifiable likelihood (probability) of data. In applying statistics to, for example, a scientific, industrial, or social problem, it is conventional to begin with a statistical population or a statistical model process to be studied. Populations can be diverse topics such as "all people living in a country" or "every atom composing a crystal". Statistics deals with all aspects of data including the planning of data collection in terms of the design of surveys and experiments. When census data cannot be collected, statisticians collect data by developing specific experiment designs and survey samples. Representative sampling assures that inferences and conclusions can reasonably extend from the sample to the population as a whole. Next

Statistical inference is based upon mathematical laws of probability. The following example will give you the basic ideas. Suppose we want to determine if a certain coint is biased. We might do a few coin tosses (sample) so that we can decide if a particular coin is equally likely to land head or tail over an infinite number of tosses (population). If we toss the coin ten times and get 6 heads and 4 tails, we might suspect the coin is biased towards heads, but we wouldn't be very confident about this, because it's not that unusual (not that improbable) to get 6 heads out of 10.

What is the statistical analysisThe statistical analysis revealed an element of our new marketing plan that was not effective so we used that information to alter our business plan. Descriptive statistics are used to describe the basic features of the data in a study. They provide simple summaries about the sample and the measures. Together with simple graphics analysis, they form the basis of virtually every quantitative analysis of data. Descriptive statistics are typically distinguished from inferential statistics. With descriptive statistics you are simply describing what is or what the data shows. With inferential statistics, you are trying to reach conclusions that extend beyond the immediate data alone. For instance, we use inferential statistics to try to infer from the sample data what the population might think. Or, we use inferential statistics to make judgments of the probability that an observed difference between groups is a dependable one or one that might have happened by chance in this study. Next

Statistical Analysis Methodology RAND

What is the statistical analysisA collection of RAND research on the topic of Statistical Analysis Methodology. A statistical analysis plan (SAP) describes the planned analysis for a clinical trial. SAPs must be carefully reviewed by statistical programmers working on the project for clarity and comprehension in order to construct analysis data sets and prepare planned Tables, Figures, and Listings. SAP review is a challenging task that requires both statistical expertise and abstract thinking skills, and is often times completed in the absence of available trial data. Statistical programmers must also develop critical evaluation and communications skills to prospectively identify issues and seek clarity with statistical colleagues on planned analyses on a trial or a development program. Statistical programmer education and training is highly variable and is derived from multiple disciplines, suggesting that comprehensive training on SAP review is an essential skill to ensure consistency and quality within the project. This Wiki provides training guidance on how a structured comprehensive SAP review and how awareness of statistics can be increased for the statistical programmer, with a resulting quality improvement of the statistical programming work products. Clinical studies are complex scientific experiments designed to provide evidence to answer questions regarding the safety and efficacy of products. Furthermore data generated as part of these clinical studies are used for regulatory applications and/or communications of study results in manuscripts, marketing materials, or other symposia. Next

Thus far we have made the case that randomized controlled experiments are the best approach available to researchers for drawing causal inferences. In the absence of experimental design, causal inference is more difficult. However, applying statistical models to observational data can be useful for understanding causal processes as well as for identifying basic facts about racial differences. Indeed, observational studies are the primary tool through which researchers have explored racial disparities and discrimination. The main goals of this chapter are to delineate the strengths and problems associated with measuring discrimination using observational studies and to identify methodological tools that are particularly promising for application in certain areas of research on discrimination.
