Use the data in cell E38, which is MS for Rows, and in cell E40, which is MS Error, to calculate Cronbach’s Alpha. Type the formula in cellB45and hitENTERto getCronbach’s Alpha. I’ve shown the formula in cellC45using theFORMULATEXTfunction so that you can understand it. =1-(E4...
When it comes to analyzing data, P-value is an essential concept that helps to determine the significance of the results obtained from regression or correlation analysis. However, calculating P-value manually can be a daunting task, with a high probability of errors. That's where spreads...
To determine whether participants interpreted the pronoun in the statements generically (as we intended) or specifically (i.e., referring to them, specifically) participants were asked to report who the pronoun in a given trial referred to, after they completed all four trials. They were able ...
To determine the required sample size, we performed a power analysis (Dattalo 2008) of a small-sized effect (0.2 SD) with a power of 85\(\%\) in a between-subjects experiment. It showed that a minimum of 277 participants were needed in total. This was in line with the suggested mini...
One explanation might be that these differing results were caused by sample differences, as the Validation Study 1 sample had a lower mean semester and included psychology students besides teacher students; however, we cannot conclusively determine how these differences affected the results. Nevertheless...
We chose our sample size to have 90% power to detect an odds ratio of 1.36; this was established by using simr with the pilot data and estimating the variance–covariance matrix. For Experiment 2, we used the data from Experiment 1 to determine the power of our hypotheses. For willingness...
1-beta is the chance to reject the null hypothesis when it is not true–a correct decision-. This is called power. Power is a function of alpha, sample size and effect (the effect here is the difference in conversion between the two landing pages, i.e. at population level the added ...
to complete the dataset before running theGeographically Weighted Regressiontool. Next, you must choose a model type based on the data you are analyzing. It is important to use an appropriate model for the data. Descriptions of the model types and how to determine the appropriate on...
one of the ways to determine if a portfolio is earning the proper return for its level of risk. If the value is positive, then the portfolio is earning excess returns. In other words, a positive value for Jensen's alpha means afund managerbeats the market with their stock-picking skills...
Alpha Ratio When you want to determine excessreturns on investment, use the alpha ratio, which refers to returns earned on investment above the benchmark return. In other words, it measures excess returns from thebenchmark index. According to Investopedia, “Alpha, often considered the active ret...
