Quesiton : A statistical method for determining the probability that research findings occurred by chance is called _____.

Answer: Test of significance

A statistical method for determining the probability that research findings occurred by chance is called _____. Social Problem . a condition or pattern of behavior that contradicts some other condition or pattern of behavior; is defined as incompatible with the desired quality of life; is caused facilitated or prolonged by social factors; involves intergroup conflict and requires social action for resolution. A method of subject selection used to attempt to prevent biases by making the sample more representative of the population. It involves identifying some of the factors (strata) present in the population such as age sex or income level and then selecting a separate sample from each stratum in the same proportions. Sample size—with larger sample sizes statistical significance is more likely to be seen. Variability in patient response or characteristics either by chance or by nonrandom factors. The smaller the variability the easier to demonstrate statistical significance. Social Research Methods/Statistical Analysis. • Regression equations are computed on the basis of a regression line: the geometric line representing with the least amount of discrepancy the actual location of points in a scattergram. • Types of regression analysis include linear regression analysis multiple regression analysis ... Probability and Statistics . Thus the relationship between probability and statistics cuts both ways - statistical analysis makes use of probability and probability calculation makes use of statistical analysis . In general we are interested to know what is the chance of an event occurring . Relative frequency method of assigning probabilities When the assumption that the outcomes of a statistical experiment are known in advance and are equally likely is not satisfied the estimation of probability for events of interest can be done by using past statistics . 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. History. In 1925 Ronald Fisher advanced the idea of statistical hypothesis testing which he called "tests of significance " in his publication Statistical Methods for Research Workers. Fisher suggested a probability of one in twenty (0.05) as a convenient cutoff level to reject the null hypothesis .
