Use The Data Set To Determine Which Statements Are Correct. Check All That Apply. 115, 120, 118, 104, 109, 148, 135, 141, 139. Hence, c)there is an outlier is not correct. The median is not 109, so the statement the median is 109 is incorrect.
104, 109, 115, 118, 120, 135, 139, 141 and 148. Therefore, the option h)the interquartile range is 28 is correct. An outlier is a data point that is more than $$1.5$$1.5 times the $$iqr$$i qr from the median.
The median of the data set is 120, so the statement the median is 120 is correct. The first step is to arrange this data set in numerical (ascending) order: $$154$$154 is greater than $$q3 + 1.5*iqr = 70 + 1.5*41 = 70 + 61.5 = 131.5$$q3+1.5∗i.
The next step then, is to identify all the statistical properties inquired in. Therefore, the option h)the interquartile range is 28 is correct. Looking at the data set below, their is no outlier present.
Sort the data points in ascending. To determine the correct statements about the given data set, we will follow a series of steps to calculate the median, quartiles, and identify any outliers. The correct statements from the data set are that the median is 120, the lower quartile is 112, the upper quartile is 140, and the interquartile range is 28.
Q3 is the median of the second half (120, 135, 139, 141, 148) = (139 + 141)/2 = 140 determine the interquartile range (iqr):
