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...
In column F, starting from cell F2, use the COUNTIF function to count how many times each sum occurs. For example, in cell F2, enter =COUNTIF(C$2:C$10001, E2) and copy this formula down to F13 viaExcel Calculate probabilities In column G, convert the counts to probabilities by divid...
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...
Use SPSS to calculate the population mean, =___, and the population standard deviation =___ , of this population for Income variable. (The standard deviation given from using Descriptive statistics option of SPSS is the sample standard deviation. You need to correct the sample standard...
Calculate the correlation coefficient of the following paired data points. How do we know when variables are meaningless to interpret in terms of mean, standard deviation, skewness and kurtosis? Explain how two-way ANOVA is basically the same as one-way ANOVA, except that the model s...
We thus needed to calculate the instantaneous mediation θ to test the mediation effect. Stolzenberg claimed [76] that when there is a non-linear relationship in the path of action of the independent variable (X) on the dependent variable (Y) through a mediator variable (M), the indirect ...
To generate a time series for the entire brain, we employed the Graph Theoretical Network Analysis toolbox to calculate the time course of each node [42]. This process entailed averaging the BOLD signals across all voxels within each node at every time point. Subsequently, the obtained time ...
and a crosshead speed of 0.75 mm/min. Each sample was measured before the test. Only samples with dimensions that met the criteria of 2 mm ± 0.01 mm were tested (6 specimens were rejected). The exact measurements of each specimen were entered into the equation to calculate the flexural st...
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...
