Question

20 representative students were selected from each of 5 schools intermediate level. The 100 selected students presented themselves to a Math Quiz. A researcher wants to prove that the averages Mathematics performance is not the same in the five schools. I know analyzed the data mediated by ANOVA.

Sources / degrees of freedom / sum of squares / squares media / Fcalculated / pvalue

Between groups - 2000

Within groups - 9500

Complete the table to answer:

1) The mean square between groups is:

2) The mean square within groups is:

3). The test calculation is:

4) The value is:

5. Conclusion:

Se seleccionaron 20 estudiantes representativos de cada una de 5 escuelas
de nivel intermedio. Los 100 estudiantes seleccionados se presentaron a un
concurso de Matemáticas. Un investigador quiere probar que los promedios
de rendimiento de matemática no es el mismo en las cinco escuelas. Se
analizaron los datos mediante ANOVA.

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
