subject 3 103 seconds
subject 4 100 seconds
subject 5 112 seconds
The median of the samples
The mean of the sample set is. ____________. The median of the sample set is ____________.

Answer 1

Answer:

Mean: 114.8

Median: 112

Explanation:

The mean is the average of the numbers so you add them all together and divide by the number of terms. The median is the middle value when the terms are in order from least to greatest.

Answer 2

Answer:

Mean of the sample set = 114.8  

Median of the sample set = 112

Explanation:

To calculate mean, add value of all samples and then divide with number of samples.

Mean of the sample set = (100+103+112+120+139)/5 = 114.8

To calculated median, arrange the values in ascending order then take the value which is at middle.

100, 103, 112, 120, 139

“112” is at the middle so,

Median of the sample set = 112
