Question

NOTE: the simple method of calculating quartiles by hand (taught in class) MUST be used for this quiz. You may use Kaddstat to check your answer. However, if the answer from your hand calculation and Kaddstat are not the same, you MUST enter your hand calculation answer. DO NOT use any complex algorithms built into calculators, or the Excel function 'quartile' Some questions list data. Type the data into Excel and use the Data Analysis or Kaddstat Boxplot for working. PLEASE MAKE SURE TO RE-CHECK ALL YOUR ANSWERS BEFORE SUBMITTING YOUR QUIZ. Ensure that all your answers are entered with the correct amount of decimal places, including the correct amount of zeros. Some web browsers may drop the zeros at the end of an answer if you save, exit and then return to the quiz (eg your browser may change your entered answer of 21.30 [to two decimal places] to 21.3 if you exit and re-enter the quiz). You must have the correct decimal places and correct number of zeros in your answer to be marked correct. Therefore, PLEASE double check all your answers directly before submitting them. These rules and tips, as well as other important rules and tips (eg NOT to use symbols such as % and $ in your answers), are listed in detail in the CML Information Sheet. Please ensure you read, understand and follow ALL these rules when completing your quiz and when you submit your quiz. This will save you losing precious marks for errors that can be easily avoided!

Answer 1

The minimum is the lowest value of the data set. It is 145 in this case.

To find Q1, Q3, and median, let's divide the data set into 2 parts. From 768 to 286 and from 215 to 145.

Q1 is the median of the lower half of the data set. It is the median of 215, 172, 162, 148, 145. Hence, Q1 = 162

Q3 is the median of the upper half of the data set. It is the median of 768, 429, 323, 306, 286. Hence, Q3 = 323

Median of the data set is its mid point. It is 262.

The maximum is the highest value in the data set. It is 768 in this case.
