Answer:
The team did not adequately formalize the software's design
Explanation:
The most logical reason for this confusion is the fact that the team did not adequately formalize the the software design.
The design approach has to do with clearly defining the architectural modules of the application. The requirements in the software requirement specification document would serve as input for the next phase. The documents are prepared and they give a definition of the overall system architecture.
The team got confused because they did not go through this phase of the 10-phase SDLC model.
Answer:
- import statistics
- def st_dev(file_name):
- with open(file_name) as file:
- data = file.readlines()
- numList = []
- for x in data:
- numList.append(int(x))
-
- return statistics.pstdev(numList)
- print(st_dev("text1.txt"))
Explanation:
The solution code is written using Python.
To ease the calculation task, we can import Python statistics module to use the pstdev method to calculate the population standard deviation of a list of numbers (Line 1).
Next, create a st_dev function that take single argument file_name (Line 3). In the function, it will open the input file and read the data line by line (Line 4-5). Create a for loop to traverse through each line of the data which is an integer and append it to numList (Line 7-8). We can pass the numList to pstdev method (Line 10) and return the resulting standard deviation value as output.
We test the function by passing a file which hold a list of integer values in each line (Line 12).
