Group the following 40 measurments of interorbiltal width of a sample of domestic pigeons into a frequency distribution and draw histogram. Data in millilitres 12.2/12.9/11.8/11.8/11.6/11.1/12.3/12.2/11.8/11.8/. 10.7/11.5/11.3/11.2/11.6/11.9/13.3/11.2/10.5/11.1/. 12.1/11.9/10.4/10.7/10.8/11/11.9/10.2/10.9/11.6. 10.8/11.6/10.4/10.7/12/12.4/11.7/11.8/11.3/11.1 find the mean standard deviation and coefficient of variation for the pigeons data given . Group the data into ten calsses and recompite the mean and standard deviation of variance and compare them with the results obtained from ungrouped data. Compute median for the grouped data
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.
