After doing so, a variable will have a mean of exactly zero but is not affected otherwise: its standard deviation, skewness, distributional shape and everything else all stays the same. After mean centering our predictors, we just multiply them for adding interaction predictors to our data....
First, we must arrange the values in ascending or descending order to find the median. Rearranged values: 2, 4, 4, 6, 18, 26. Then, we identify the number in the middle as the median. If there are even numbers of values, we calculate the mean of the values in the middle to fin...
Back to Top How to Find an Interquartile Range in SPSS Like most technology, SPSS has several ways that you can calculate the IQR. However, if you click on the most intuitive way you would expect to find it (“Descriptive Statistics > Frequencies”), the surprise is that it won’t list...
Clearly, there are 3 dimensions with responses above the mid-point, revealing a slight negative skewness, i.e., participants situated themselves more between “3-Neither agree nor disagree” and “5-Agree strongly”: agreeableness, conscientiousness and openness, confirming the results found in our...
Answer to: Explain how two-way ANOVA is basically the same as one-way ANOVA, except that the model sum of squares is partitioned into three parts...
The statistical assumptions of normality, linearity, and singularity were analyzed. It was observed that the histograms, skewness and kurtosis values and significance tests (Shapiro–Wilk) indicated a normal distribution. Deviations from multivariate normality are innocuous when all the variables meet this...
The model’s fit indices were above the cut-off points commonly established in the literature: RMSEA values were below 0.08, with an upper limit below 0.10, and CFI and TLI values were above 0.90 [50]. The CFI (comparative fit index) and TLI (Tucker Lewis Index) indices calculate the ...
The normality of distribution of the mYFAS score was confirmed via a calculation of the skewness and kurtosis; values for asymmetry and kurtosis between −1 and +1 are con- sidered acceptable in order to prove normal univariate distribution [34]. These conditions consolidate the assumptions of...
Previous research has found that frugal and price-conscious consumers are more likely to engage in second-hand luxury consumption as these consumers calculate the monetary value and justify their purchases from a rational point of view [1,10]. Thus, the following hypothesis was proposed: Hypothesis...
