Binned Frequency Tables. Use the given bin sizes to make a frequency table for the following data set: 89 67 78 75 64 70 83 95 69 84 77 88 98 90 92 68 86 79 60 96 Include columns for relative frequency and cumulative frequency. Use 10-point bins (90 to 99, 80 to 89, etc.).
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.
Binned Frequency Tables. Use the given bin sizes to make a frequency table for the following data set:
| 89 | 67 | 78 | 75 | 64 | 70 | 83 | 95 | 69 | 84 |
| 77 | 88 | 98 | 90 | 92 | 68 | 86 | 79 | 60 | 96 |
Include columns for relative frequency and cumulative frequency.
Use 10-point bins (90 to 99, 80 to 89, etc.).
