Python Data Statistics Probability
100
Why do we use python?
It's easy and free
100
Three decline models used in the course
Exponential, Hyperbolic, harmonic
100
What does descriptive statistics refer to?
Descriptive statistics refers to quantities such as
mean, median, mode, standard deviation, skewness,
kurtosis, etc. which describe a given data or distribution.
100
What is a sample space?
The sample space of an experiment is the set of all possible outcomes for that experiment
200
What type of language is python?
Python is a language that is interpreted, intuitive, interactive, dynamic, and object oriented
200
What is the difference between accuracy and precision?
Accuracy refers to how closely a value agrees with the true or exact value. Precision refers to how closely values agree with each other.
200
What is the first moment of inertia?
Mean, the central tendency in data
200
What is conditional probability?
A probability that is based on a part of a sample space
300
What value will be displayed by the print statement when the following lines of code are run?
length = 10

breadth = 10 #breadth refers to the width
area = length * breadth
height = 5
print(area*height) #volume = area*height
500
The first line of code sets the length to 10, the second sets the breadth to 10, and the fourth sets the height to 5. The third line will multiply the length by the breadth, and assign the result (which is 100) to area. The last line will print the product of the area and height as 500 (that is, 100*5).
300
What are jointly distributed variables?
When two or more random variables are associated with each item in a population
300
What is the second moment of inertia?
Standard deviation, it is a measure of the dispersion or variability
300
What are random variables?
Variables described by probability distributions
400
x = 15
if x > 10:
if x >= 20:
print("Above 10 and greater than or equal to 20")
else:
print("Above 10 but not above 20.")
The code above will print
Above 10 but not above 20
400
What is a round off error?
It's when numbers are always stored as approximate
values in computer memory because only a certain
level of precision can be physically stored on these
devices
400
What is the 4th moment of inertia?
Kurtosis, Measure of the fatness
or thickness of the tail in
a distribution
400
What are continuous probability distribution examples?
Normal, lognormal, and uniform probability distributions
500
a, b = 0, 0
if a > b:
print("a is greater than b")
elif (a==b):
print("a is equal to b")
else:
print("a is less than b")
The code above will print:
A is equal to b
500
What is a truncation error?
These are errors that occur because some number
of steps have been shortened
500
What is the third moment of inertia?
Skewness, Measure of asymmetry
in a distribution
500
What are discrete probability distribution examples?
Binomial, Poisson and Multinomial distributions
