In a one-way ANOVA, the __________ is calculated by taking the squared difference between each person and their specific groups
guapka [62]

Answer:

In a one-way ANOVA, the SS_{within} is calculated by taking the squared difference between each person and their specific groups mean, while the SS_{between} is calculated by taking the squared difference between each group and the grand mean.

Step-by-step explanation:

The one-way analysis of variance (ANOVA) is used "to determine whether there are any statistically significant differences between the means of two or more independent groups".

The sum of squares is the sum of the square of variation, where variation is defined as the spread between each individual value and the mean.

If we assume that we have p groups and each gtoup have a size n_j then we have different sources of variation, the formulas related to the sum of squares are:

SS_{total}=\sum_{j=1}^{p} \sum_{i=1}^{n_j} (x_{ij}-\bar x)^2

A measure of total variation.

SS_{between}=\sum_{j=1}^{p} n_j (\bar x_{j}-\bar x)^2

A measure of variation between each group and the grand mean.

SS_{within}=\sum_{j=1}^{p} \sum_{i=1}^{n_j} (x_{ij}-\bar x_j)^2

A measure of variation between each person and their specific groups mean.

Last year, I had 92 APES students and this year I will have 63 APES students. By what percentage will the population of APES stu
Reptile [31]

Answer:

31.52% increase (decrease)

Step-by-step explanation:

To find the decrease in the percentage of students from the previous year to the current year, you must establish a baseline to be your maximum (100%).  For this we'll use the 92 students.  From here, we need the current 63 students to establish the current percentage.

Simply:

63/92 == .6848 == 68.48%

So our current percentage of students is 68.48%.  We want the decrease of the students compared to the previous percentage so we'll need to do the maximum minus the current to get the change (or the decrease).

100% - 68.48% = 31.52%

Thus, the population increase (decrease) for this year is 31.52%.
