Answer:
C. factor analysis.
Explanation:
Factor analysis: The term factor analysis is referred to as a statistical method that is used to demonstrate the variability of the correlated, observed variables concerning the possibly unobserved variables of lower number knows as factors.
Factor analysis examines joint variations concerning latent unobserved variables.
In other words, factor analysis is used to identify questions in any survey that reflect abstract variables or broader dimensions known as factors that are independent of one another.
The correct answer is Elaboration
Explanation: To elaborate means to carry out activities that allow the apprentice to make some symbolic construction about the information he is trying to learn with the purpose of making it meaningful.
Elaboration Strategy is a way to help students.
Answer:
When the program raises an exception as soon as the end of the is reached, this exception makes the input process difficult. We have no specific or clear way to encounter the end of the file before the exception is raised.
So to resolve this Python's try except statement can be used. This statement catches the exception and enables the program to recover. We can construct an input file loop. This loop will keep loading objects until the end of the file is detected. Below is an example to load objects from the file into a new list.
lst=list()
fileObj = open("item.dat","rb")
while True:
try:
item= pickle.load(fileObj)
lst.append(item)
except EOFError:
fileObj.close()
break
print(lst)
The file name is item.dat and new list is named as lst. When the end of the file is encountered EOFError is raised and except clause with EOFError closes the input file and breaks out of the loop.
