tyres. From the past experience‚ it is known that the standard deviation of the load is 4000kgs. A sample of 100 tyres was selected and tests were carried out. The result showed that mean stress capacity of the sample is 79‚600 kgs. If the supplier uses a significance level of 5% in testing‚ do the tyres meet stress requirements? Also‚ find the limits of the acceptance region (or confidence limits). Q3) A random sample of 400 flower stems has indicated that the average length of a stem is 10cm

CORRELATION RESEARCH DEFINITION: Correlational research tests for statistical relationships between variables. The researcher begins with the idea that there might be a relationship between two variables. She or he then measures both variables for each of a large number of cases and checks to see if they are in fact related. The relationship of interest could be either a D relationship or an R relationship‚ so this might involve making a bar graph and computing D or making a line graph

Causation and Correlation Jennifer PSY/285 Darren Iwamoto July 17‚ 2013 Causation and Correlation Correlation does not imply causation. According to “statistical Language Correlation and Causation” (Correlation is a statistical measure (expressed as a number) that describes the size and direction of a relationship between two or more variables. A correlation between variables‚ however‚ does not automatically mean that the change in one variable is the cause of the change in the values of

Coefficient of Linear Expansion Introduction With few exceptions materials expand somewhat when heated through a temperature range that does not produce a change in phase (i.e. melting‚ freezing‚ boiling etc.). The added heat increases the average amplitude of vibration of the atoms in the material‚ which increases the average separation between the atoms. Although this effect is small‚ it is very important in any application that involves using different materials in an environment where they

Cause and Correlation Vergia Wallace PSY/285 March 8‚ 2013 Dr. Elizabeth Brook Morford The difference between causation and correlation is extremely significant in systematic thought. These two notions get confused with one another whether it is a misinterpretation or having the aspiration to provide a reasonable description for scientific observations. As a result it is critical to have the understanding of the difference between the two concepts. In this writing I will compare and contrast

This is accomplished through a peculiar set of integrated employment policies‚ programmes and practices intruded in an organisational and social context (Bratton and Gold‚ 2012). The new HRM model is created from the strategies that contribute mutuality – reciprocal targets‚ influence‚ respect and responsibilities. The theory claims that these methods of mutuality educe involvement in a common activity
