A Guide to Effective Writing, Note-Taking, and Literary Analysis
What are the Basic Steps of Writing a Paragraph?
1. Topic Selection
Keeping in mind broad areas of interest, the topic should be selected first. It should be one in which the writer is most familiar, involving their personal knowledge and experience. The writer needs to think clearly and have a complete understanding of the topic before they write.
2. Statement of Idea
The most dominant idea should be stated in the introductory statement or sentence. The subsequent statements in the paragraph should

What is Statistics?
Statistics is a branch of mathematics that deals with the collection, analysis, interpretation, presentation, and organization of data. It provides tools and methods for making sense of data and drawing meaningful conclusions from it. Statistics plays a crucial role in various fields, including scientific research, business, economics, healthcare, and social sciences.

8A Data
Data can be either numerical (a symbol representing a number) or categorical (data that can be grouped according to a particular type).
Numerical data can either be discrete (can only be particular numerical values) or continuous (can be any numerical value in a range).
Categorical data is non-numerical data that can be grouped into ‘categories’.
Data can be represented as a graph or a table.
Common types of graphs include:

A tally is a tool used for counting as results are gathered.

Bisection Method
The bisection method is a numerical technique used to find the roots of a continuous function. It is a type of bracketing method, which means it requires two initial guesses that bracket (i.e., surround) the root. The function must change signs over this interval, indicating that there is at least one root in that interval (by the Intermediate Value Theorem).
Advantages
It’s a simple, straightforward algorithm that’s easy to understand and implement. Its robustness makes it suitable

Introduction to Statistics
Statistics refers to the body of techniques used for collecting, organizing, analyzing, and interpreting data. It is used in various fields to help make better decisions by understanding variation, patterns, and relationships in data.
Types of Data
Data can be classified into two main types:
- Quantitative: Values expressed numerically.
- Continuous: Infinite range of variables, decimals. Example: Grade on an exam.
- Discrete: Whole numbers. Example: Number

Algebraic Expressions
Like Terms
You can only add and subtract like terms (terms that have the same letter or power). For example:
- 8 – 3w + 7 – 2w = 8 + 7 = 15 -3w – 2w = -5w = 15 – 5w
Multiplying and Dividing Like Terms
When multiplying or dividing like terms, multiply or divide the numbers first, then add the letters after. Letters must be in alphabetical order.
- Multiplication Example: 5w x 6v = 5 x 6 = 30 then add the letters in alphabetical order: 30vw
- Division Example: 10w / 2w = 10 / 2 = 5
