What does the idiom 'a piece of cake' mean?

Something that is very easy to do.

What is the difference between the commonly confused words 'affect' and 'effect'?

'Affect' is usually a verb meaning to influence; 'effect' is usually a noun meaning the result of a change.

What is the difference between 'principal' and 'principle'?

'Principal' means main/chief or the head of a school (and a sum of money); 'principle' is a fundamental rule or belief.

What is the difference between 'stationary' and 'stationery'?

'Stationary' means not moving; 'stationery' means writing materials such as paper and pens.

Identify a synonym and an antonym for the word 'abundant'.

Synonym: plentiful/copious; Antonym: scarce/sparse.

What does the word 'ubiquitous' mean?

Present, appearing, or found everywhere.

What is a synonym for the word 'meticulous'?

Careful, precise, or scrupulous (showing great attention to detail).

In reading comprehension, what is the difference between the 'main idea' and a 'supporting detail'?

The main idea is the central point the author wants to convey; supporting details are facts, examples, or reasons that explain or back up the main idea.

In reading comprehension, what does it mean to 'infer' from a passage?

To draw a logical conclusion based on evidence and reasoning in the text rather than on information stated explicitly.

What is the difference between a passage's 'tone' and its 'theme'?

Tone is the author's attitude or emotional quality (e.g., sarcastic, optimistic); theme is the underlying central message or idea of the text.

In narrative sequencing, what is the typical chronological order of a story's plot elements?

Exposition (introduction), rising action, climax, falling action, and resolution (denouement).

What are common signal words used to identify sequence or chronological order in a narrative?

Words such as 'first', 'then', 'next', 'after', 'before', 'meanwhile', and 'finally'.

In data interpretation, what does the term 'data interpretation' broadly involve?

Analyzing data presented in tables, graphs, or charts to draw conclusions, compare quantities, and compute values such as totals, averages, ratios, and percentages.

What type of data is best represented by a bar graph?

A bar graph best represents and compares discrete categories or groups using rectangular bars whose lengths are proportional to the values they represent.

What does a pie chart represent, and what is the total of all its sectors?

A pie chart represents parts of a whole as sectors of a circle; all sectors together total $100\%$ or, in angular terms, $360^{\circ}$.

In a pie chart, what is the formula to convert a category's percentage share into its central angle?

$\text{Angle} = \frac{\text{Value of category}}{\text{Total}} \times 360^{\circ}$, or equivalently $\text{percentage} \times 3.6^{\circ}$.

What type of graph is best for showing a trend or change in a quantity over continuous time?

A line graph, which plots data points connected by lines to show trends or continuous change.

What is a histogram and how does it differ from a bar graph?

A histogram displays the frequency distribution of continuous data using adjacent bars over intervals (no gaps), whereas a bar graph compares discrete categories with gaps between bars.

What is the formula for percentage change between an old value and a new value?

$\text{Percentage change} = \frac{\text{New value} - \text{Old value}}{\text{Old value}} \times 100\%$.

How do you compute the average (arithmetic mean) of a set of $n$ data values?

$\bar{x} = \frac{1}{n}\sum_{i=1}^{n} x_{i}$, i.e., the sum of all values divided by the number of values.

In data interpretation, how is the ratio of two quantities $a$ and $b$ expressed and simplified?

It is written as $a:b$ or $\frac{a}{b}$ and simplified by dividing both terms by their greatest common divisor.

What is the difference between a 2-dimensional plot and a 3-dimensional plot?

A 2-D plot represents data using two axes (x and y), while a 3-D plot uses three axes (x, y, and z) to represent a relationship among three variables.

In a 2-D Cartesian plot, what do the x-coordinate and y-coordinate of a point $(x, y)$ represent?

The x-coordinate is the horizontal distance from the origin (abscissa) and the y-coordinate is the vertical distance from the origin (ordinate).

What is a scatter plot used for in data interpretation?

A scatter plot displays individual data points for two variables to reveal correlation, clustering, or trends between them.

On a map, what does the 'scale' indicate?

The scale shows the ratio between a distance on the map and the corresponding actual distance on the ground (e.g., $1:50000$).

If a map has a scale of $1:100000$, what actual distance does $3\text{ cm}$ on the map represent?

$3 \times 100000 = 300000\text{ cm} = 3\text{ km}$.

In a data table, what is the purpose of column and row headers?

Headers label the categories of data so that each cell's value can be identified by the intersection of its row and column.

What does the idiom 'to beat around the bush' mean?

To avoid talking about the main point or to speak indirectly, evasively.

In English usage, what is the difference between 'fewer' and 'less'?

'Fewer' is used with countable nouns (fewer books); 'less' is used with uncountable nouns (less water).

What is the difference between an independent clause and a dependent (subordinate) clause?

An independent clause expresses a complete thought and can stand alone as a sentence; a dependent clause does not express a complete thought and relies on a main clause.
