Explanation Calculation: The first quartile ( Q 1 ) is considered to be the median of the lower half of the data set. The second quartile ( Q 2 ) is considered to be the median of the entire data set. The third quartile ( Q 3 ) is considered to be the median of the upper half of the data set. To obtain the quartiles, first arrange the datafrom the smallest to the largest, asshown below: 55 , 73 , 75 , 80 , 81 , 85 , 90 , 93 , 93 , 98 The count of observation n = 10 is even. First quartile ( Q 1 ) is the median of first five observations and is calculated as shown below: For first quartile, consider the left half of the data set: 55 , 73 , 75 , 80 , 81 The first quartile is calculated as shown below: First quartile ( Q 1 ) = ( 5 + 1 2 ) th observation = ( 6 2 ) th observation = 3 rd observation The 3 rd observation in the first five observations of the data set is 75 . So, the first quartile ( Q 1 ) is 75 . The second quartile ( Q 2 ) is the median of the entire data set. For the second quartile, consider the entire data set: 55 , 73 , 75 , 80 , 81 , 85 , 90 , 93 , 93 , 98 The second quartile is calculated as shown below: Second quartile ( Q 2 ) = ( 10 + 1 2 ) th observation = ( 11 2 ) th observation = 5

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 o…

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 compar…
