Quick Practice - Try a Few Questions First Pick a chapter below, answer a few questions instantly, then jump to the full set list for more. Q1.Which SQL clause is used to filter rows based on a specified condition? Answer: (b) WHERE. It lets you narrow down the result set to only the rows that satisfy a given condition.
Q2.Which SQL aggregate function returns the total number of rows matching a query? Answer: (b) COUNT(). It's commonly used to quickly find out how many records satisfy a particular condition, without needing to look at the individual rows.
Q3.The GROUP BY clause in SQL is primarily used to: Answer: (b) Group rows sharing a common value so aggregate functions can be applied to each group. For example, it lets you find the total sales for each individual product category.
Q4.Which SQL function is used to find the highest value in a column? Answer: (b) MAX(). It scans through the specified column and returns the largest value found.
Q5.The HAVING clause in SQL is used to: Answer: (b) Filter groups after the GROUP BY clause has been applied. It's used specifically because WHERE cannot filter based on the result of an aggregate function.
Q1.In Pandas, a Series is best described as: Answer: (b) A one dimensional labelled array capable of holding any data type. It's one of the two core data structures in Pandas, alongside the DataFrame.
Q2.A Pandas DataFrame is essentially: Answer: (b) A two dimensional, tabular data structure with labelled rows and columns. It closely resembles a spreadsheet or a table in a relational database.
Q3.Which Pandas function is commonly used to read data from a CSV file into a DataFrame? Answer: (a) pd.read_csv(). This is one of the most frequently used functions when working with tabular data files in Pandas.
Q4.Which attribute of a DataFrame returns the number of rows and columns as a tuple? Answer: (b) .shape. It returns a tuple in the form (number of rows, number of columns), which is often the first thing checked after loading a dataset.
Q5.The head() function in Pandas is used to: Answer: (b) Display the first few rows of a DataFrame, by default the first five. It's a quick and commonly used way to get a first look at a dataset.
Q1.Which Pandas function is used to handle missing values by removing rows or columns containing them? Answer: (b) dropna(). It removes rows or columns with missing values, depending on which axis is specified.
Q2.The fillna() function in Pandas is primarily used to: Answer: (b) Replace missing values with a specified value. This is often preferred over simply dropping rows, especially when the dataset is small and every row genuinely matters.
Q3.Which function is used to combine two DataFrames based on a common column, similar to a SQL join? Answer: (b) merge(). It allows DataFrames to be combined using logic very similar to joins in relational databases.
Q4.The groupby() function in Pandas is used to: Answer: (b) Split data into groups based on some criteria, so operations can be applied to each group. It's often paired with aggregate functions like sum() or mean() to summarise data by category.
Q5.Which Pandas method is used to sort a DataFrame based on the values in a particular column? Answer: (a) sort_values(). It lets you sort a DataFrame in ascending or descending order based on one or more specified columns.
Q1.Which Matplotlib function is commonly used to create a simple line plot? Answer: (b) plt.plot(). It's the most basic and widely used function for drawing line graphs in Matplotlib.
Q2.Which function in Matplotlib is used to display the final plot on screen? Answer: (b) plt.show(). Without calling this function, the figure you've built usually won't actually be displayed in most environments.
Q3.To create a bar chart in Matplotlib, which function would you typically use? Answer: (a) plt.bar(). It draws rectangular bars whose lengths are proportional to the values they represent.
Q4.Which Matplotlib functions are used to label the x-axis and y-axis of a plot? Answer: (b) plt.xlabel() and plt.ylabel(). These add descriptive text along each axis, making the chart much easier for a reader to interpret correctly.
Q5.A pie chart in Matplotlib is created using which function? Answer: (b) plt.pie(). It's particularly useful for showing how individual parts contribute to a whole, expressed as proportions.
Q1.HTTP stands for: Answer: (a) HyperText Transfer Protocol. It's the underlying protocol that governs how web browsers and servers communicate with each other.
Q2.A URL, or Uniform Resource Locator, is primarily used to: Answer: (b) Specify the address of a resource on the internet. It typically includes the protocol, domain name, and the specific path to the resource being accessed.
Q3.Which of these is an example of a web browser? Answer: (b) Google Chrome. Web browsers are the software applications used to access and display webpages, and other common examples include Firefox and Safari.
Q4.HTTPS differs from HTTP mainly because HTTPS: Answer: (b) Adds a layer of encryption for secure data transmission. This is exactly why websites handling sensitive information, like banking or shopping sites, use HTTPS rather than plain HTTP.
Q5.A web server is best described as: Answer: (b) A computer or program that stores and delivers webpages to users on request. When you type a website address, your browser sends a request to a web server, which then responds with the requested page.
Q1.Which of these is a common example of an intellectual property right relevant to software? Answer: (a) Copyright. It legally protects original works, including software code, from unauthorised copying or distribution.
Q2.Cyberbullying refers to: Answer: (b) The use of digital platforms to harass, threaten, or intimidate someone. It has become an increasingly serious concern, especially given how much time young people now spend on social media and messaging platforms.
Q3.Which of these practices helps protect personal data and maintain online privacy? Answer: (b) Using strong, unique passwords and being cautious about what personal information is shared online. Basic digital hygiene like this significantly reduces the risk of accounts being compromised.
Q4.The digital divide refers to: Answer: (a) The gap between people who have easy access to digital technology and those who do not. This divide can be shaped by factors like income, location, infrastructure, and education, and it has real consequences for opportunity and access to information.
Q5.E-waste refers to: Answer: (a) Discarded electronic devices and equipment. Improper disposal of e-waste can release harmful substances into the environment, which is why responsible recycling has become an increasingly important issue.
