The steps in testing a research hypothesis‚ to compare the means of two or more groups‚ and to calculate the correlation between two variables. Testing a Research Hypothesis The hypothesis process has five steps. It is necessary to follow these steps to research any issue or question. Not following the steps or conducting them out of order could result in poor results. The purpose of testing a research hypothesis is to prove or disprove the research question. ("Research Hypothesis"‚ 2015). The five

discussions were how hypothesis testing is crucial to determining if the hypothesis is valid or false. One way to know if the hypothesis is valid is to determine the null hypothesis‚ which the opposite of the original theory‚ and tests against the alternative hypothesis‚ which correlates with the original hypothesis. To establish if the null hypothesis is valid statistical tests can help compare the means from two groups‚ and the results will verify if the theory is correct. These statistical tests‚ including

ABSTRACT: WidgeCorps’s management team had a lack in understand of some of the key multivariate statistical techniques used by many companies to measure how variables react with one another. This paper will discuss how three of these techniques are commonly used and provides a recommendation for the company to use as they move forward with research and development of new products. This paper also compares and contrasts the different multivariate techniques. KEYWORDS: multivariate techniques‚ Chi-Square

Functions of statistics Applications of statistics. Ans:Statistics plays an important role in almost every facet of human life. In business context‚ managers are required to justify decisions on the basis of data. They need statistical models to support these decisions. Statistical skills enable managers to collect‚ analyse and interpret data in order to take suitable decisions. Defination of statistics. “Statistics is a science which deals with the method of collecting‚ classifying‚ presenting‚ comparing

like to have a detailed report on the possible causes‚ if any‚ for the shortage in the amount of soda or if the claim is not supported explain how to mitigate the issue in the future. In order to statistically find a cause in the shortage a hypothesis testing is conducted by finding the mean‚ median‚ and standard deviation for ounces in the bottles. Constructing a 95 percent interval will establish the mean of the population since the mean of the population is not known. There are thirty soda

useful for understanding statistical behaviors of random quantities. It plays a role in a number of widely-used statistical analyses‚ including the Student ’s t-test for assessing the statistical significance of the difference between two sample means‚ the construction of confidence intervals for the difference between two population means‚ and in linear regression analysis. Statistical significance is “measuring the likelihood that an event occurs by chance” (Statistical Assessment Service‚ 2000)

class’s objectives were to apply the steps in testing a research hypothesis‚ to compare the means of two or more groups‚ and to calculate the correlation between two variables. Learning Team D’s members have reflected on each of these issues and share their insights on these objectives. Testing a Research Hypothesis The purpose of testing a research hypothesis is to prove or disprove the research question. The first step in testing a research hypothesis is to state the problem in the form of a question

error free. In other words‚ if something has often happened in the past‚ it will likely happen in the future (Lee & Baskerville‚ 2003). In research that is extremely important because once researchers have collected enough data to support their hypothesis‚ they can develop a premise to predict the outcome in similar situations with a certain degree of accuracy (Lee & Baskerville‚ 2003). In order to increase our confidence in the generalizability of a study‚ it would have to be repeated with the
