Construct a dotplot for the given data. 1.2, 1.0, 0.8, 0.9, 0.8, 0.8, 1.1, 1.0, 2.1, 1.3, 0.9, 0.8, 0.8, 0.9,0.9 AUSE SALT 00.5 1.0 1.5 2.0 2.5 1.0 Q 00.5 1.5 2.0 2.5 . .. 00.5 1.0 1.5 2.0 2.5 1.0 0.5 1.5 2.0 2.5 Describe the shape of the distribution and look for any outliers. O The data is skewed left with one unusually small outlier. O The data is skewed left with no obvious outliers. O The data is skewed right with one unusually large outlier. O The data is mound shaped with no obvious outliers. O The data is mound shaped with one unusually small and one unusually large outlier,
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.
