Question

the following were calculated from the times (in minutes) that 10 individuals reported spending on the internet each day.
mean: 87 median: 72 mode: 72 range: 75 iqr: 30
what would these values be if the data in the set were converted to hours by dividing each individuals time by 60?

• press each hotspot.
• label the corresponding number below with the requested value.

press to hear a reminder or hint for this problem.
if you multiply or divide all data values in a set by the same number, the measures of center and dispersion change by the same factor.
mean: 1 median: 2 mode: 3 range: 4 iqr: 5

Explanation:

Step1: Calculate new mean

Original mean is \(87\). Divide by \(60\): \(87\div60 = 1.45\)

Step2: Calculate new median

Original median is \(72\). Divide by \(60\): \(72\div60 = 1.2\)

Step3: Calculate new mode

Original mode is \(72\). Divide by \(60\): \(72\div60 = 1.2\)

Step4: Calculate new range

Original range is \(75\). Divide by \(60\): \(75\div60 = 1.25\)

Step5: Calculate new IQR

Original IQR is \(30\). Divide by \(60\): \(30\div60 = 0.5\)

Answer:

Mean: \(1.45\), Median: \(1.2\), Mode: \(1.2\), Range: \(1.25\), IQR: \(0.5\)
