Parametric statistics

Estimating the mixing density of a mixture distribution remains an interesting problem in the statistics literature. Stochastic approximation (SA) provides a fast recursive way for numerically maximizing a function under measurement error. Using suitably chosen weight/step-size the stochastic approximation algorithm converges to the true solution, which can be adapted to estimate the components of the mixing distribution from a mixture, in the form of recursively learning, predictive recursion method

Slope class (visual interpretation) (fig-1) shows that according to our model for the area less than or equal to 5° is flat, so the majority of areas falls within less than 5° areas. It means that only some areas fall within greater than 5°. The statistical information (fig-2) of slope class shows that the min. slope is 0°, max is 31.36° and the mean is < 4°. Therefore, generally the majority of the slope areas are low. Figure 1: Slope classify area Figure 2: Classification Information Model

This report aimed to replicate Stroop's (1935) experiment. Using the repeated measures design and a sample of 20 students, differences in verbal reaction times on two tests were observed. The one-tailed hypothesis predicted that it would take longer to say words in the Cc, this is the conflicting condition where the colour of the word differs from the colour that the word describes. It was found that, using the t-test for related data, this hypothesis could be accepted as

Introduction The high tech age brings at a fast pace through different sources like TV, radio, internet, newspapers, magazines as well wanted or unwanted phone calls, instant message, social network messages, web searches, emails etc. One of the advantage of having 24/7 virtual office is businesses can capitalize on the evolving nature of the office by striking a balance that combines virtual and physical work and space which could ultimately increase productivity and lower costs without sacrificing

Testing is not a strategy but it is a biggest challenging technology and it is more essential for growing businesses of all types and sizes. Testing means to unearth the defects early, which were made during or before the development phase. Testing is essentially needed to get the customer satisfaction in any business. Testing Team should be represented in the early phase of the software advancement life cycle, the expense of fixing the bug is bigger if testing is not done in prior stage and bugs

experimental conditions (e.g. male and female or public and private banks) and different participates have been used in each condition (e.g. SECI and innovation processes). Independent t-test table yielded by PASW normally mentions two rows for the test statistics: one row is labelled Equal variance assumed, while the other is labelled Equal variances not assumed. Which row is considered is based on the significant of Levene's test for Equality of Variances. Therefore, if the Levene’s test is significant

It may also result in academic dismissal from the University.

A STUDY ON TRAFFIC RULES VIOLATIONS IN CHENNAI (VANDALUR AND PERANGALUTUR) Submitted By: Praveen Kumar A, MBA. INTRODUCTION Violations in traffic laws are very common in a highly populated country like India. The conditions are even worse in metro cities like Delhi, Mumbai Bangalore and Chennai. The accidents associated with these violations cause a huge loss to life and property. Same is the case in Chennai. Being a metro city and a highly populated one also, has a lot of road

measurement: nominal, ordinal, interval, ratio, (3) Number of groups, and if they are correlated (dependent) or independent, (4) Number of variables, and know which is the dependent and independent variable, and (5) Know when to choose a parametric versus a non-parametric test. The flowchart and the Appendix E section of the book on How to Use SPSS eighth edition of Brian Cronk (2014), was used as a guide to answer the questions below. Answer this question for the four studies below: Which statistical

sometimes called distribution-free tests because they are based on fewer assumptions (e.g., they do not assume that the outcome is approximately normally distributed)”. (,"Boston University School of Public Health " 2016, p. 1). The t-test is “a parametric statistical test for comparison of the means of two independent groups.” (Kellar & Kelvin, 2013, p. 464). According to the University of the West of England (UWE), “Correlation is a technique for investigating the relationship between two quantitative
