Python Institute PCED - Certified Entry-Level Data Analyst with Python Sample Questions (Q37-Q42):

NEW QUESTION # 37
Which of the following statements about Python functions are correct? (Choose two.)

A. Positional arguments must be passed in the order defined, while keyword arguments can be passed in any order using their parameter names.
B. passexecutes the function body and returns its result.
C. Default parameters must always come before required ones in the parameter list.
D. Functions can only return numeric values or strings.
E. A function cannot call itself or be passed as an argument to itself.
F. If a function does not contain a returnstatement, it returns Noneby default.

Answer: A,F

Explanation:
Positional arguments are matched to parameters by their position, so they must follow the defined order, while keyword arguments are matched by name and can be provided in any order. If a function completes without an explicit return statement, Python returns None automatically.

NEW QUESTION # 38
The following chart shows how a student spends 24 hours in a day:

Which statements are most accurate? (Choose two.)

A. Commuting is the second most time-consuming activity.
B. More time is spent commuting than on leisure.
C. Sleep and school take up the majority of time in a day.
D. Leisure and meals combined equal the time spent at school.
E. School and homework together take up half of the day's time.
F. Leisure accounts for a moderate portion of the student's daily schedule, larger than commuting but smaller than the time spent at school.

Answer: C,F

NEW QUESTION # 39
You are creating a presentation slide to communicate findings about student stress levels across four categories over a six-month period. You include the following line graph in your presentation:

Your goal is to help your audience clearly understand trends in stress levels over time.
What is the highest problem with this visual presentation? Select the best answer.

A. The graph doesn't explain what each stress level means or show exact values for each month, which limits interpretation.
B. The lines are too light and similar in color, making it difficult to distinguish between trends.
C. The months should be replaced with week numbers to provide more detailed insight.
D. The chart should be in 3D format to show depth and highlight differences more clearly.
E. The font used in the chart is hard to read; using larger, uppercase text would improve clarity.

Answer: B

Explanation:
The lines are very light and visually similar, making it difficult to clearly distinguish between the different stress level trends, which directly reduces the effectiveness of the visualization in communicating patterns over time.

NEW QUESTION # 40
Which task is traditionally or typically performed by a data analyst, and not by a data scientist or analytics specialist? Select the best answer.

A. Developing machine learning algorithms to predict user behavior.
B. Recommending pricing strategies using predictive modeling and A/B testing.
C. Creating summary tables and charts to describe patterns in historical data.
D. Designing a data pipeline to ingest and process real-time sensor data.

Answer: C

Explanation:
Creating summary tables and charts to describe patterns in historical data is a core responsibility of a data analyst, focusing on descriptive analytics and reporting rather than building predictive models, machine learning systems, or engineering data pipelines.

NEW QUESTION # 41
A Python script includes the expression not False and True. The developer is unsure how logical operators are evaluated in terms of precedence. What will be the final Boolean result of this expression?

A. Error
B. False
C. True
D. None

Answer: C

Explanation:
The not operator has higher precedence than and, so not False becomes True first. Then True and True is evaluated, resulting in True as the final Boolean value.

NEW QUESTION # 42
