A scientist collects these measurements: 0.90,0.85, 0.64,0.94, 0.99, −0.02,0.56,,0.15, 0.73, 0.72, 0.89, 1.72, 0.52 Which statement is correct? A.The data value −0.02 is an outlier because it is the only number less than 0.00. b.The data value 1.72 is an outlier because it is greater than 1.5×IQR above the third quartile. C.The data value 1.72 is an outlier because it is the only number greater than 1.00 d.The data value −0.02is an outlier because it is less than 1.5×IQR below the first quartile.
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.
