d = Refer to exhibit 3, If at 99% confidence level (alpha = 0.01) we want to determine whether or not the means of population are equal, the critical value of F (Fcritical Value is, usinf F table): 2.10 3.90 2.62 2.18
Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.
Exhibit 3: (MAINLY WANT "D" answered)
Part of an ANOVA table is shown below. Data is taken from 6 groups with each group containing 5 participants.
| Source of Variation | SUM of Squares | Degrees of Freedom | Mean of Squares | F |
| Treatments | 250 | 5 | MSTR?? | 10 |
| Error | 120 | 24 | 5 | |
| Total | SST??? | DF Total? |
Q23a = Refer to exhibit 3 the SST is:
b = Refer to exhibit 3 the DF total is:
c = MSTR is?
d = Refer to exhibit 3, If at 99% confidence level (alpha = 0.01) we want to determine whether or not the means of population are equal, the critical value of F (Fcritical Value is, usinf F table):
2.10
3.90
2.62
2.18
