Cevap

29.5
Filtering the dataset for startups in the Software sector yields 6 revenue figures: 14M,14M, 18M, 24M,24M, 35M, 42M,and42M, and 52M. Sorting these values in ascending order gives: 14, 18, 24, 35, 42, 52. Since N=6N = 6 is an even number, the median is the arithmetic mean of the 3rd and 4th values: 24+352=29.5\frac{24 + 35}{2} = 29.5.

Adım Adım Çözüm

1
Filter the table for startups in the Software sector.
Identified 6 Software startups with revenues of 14M,14M, 42M, 35M,35M, 52M, 24M,and24M, and 18M.
The question specifies restricting calculations to startups in the Software sector.
2
Sort the filtered revenues in ascending numerical order.
Sorted list: 14, 18, 24, 35, 42, 52.
Determining the median requires ordering data from smallest to largest.
3
Calculate the median for the even dataset (N=6N = 6).
The two central numbers are the 3rd value (24) and the 4th value (35). The median is 24+352=29.5\frac{24 + 35}{2} = 29.5.
When NN is even, the median is the average of the two middle elements.
