Statistics Topics Tested On Aleks

The online Assessment and Learning in Knowledge Spaces (ALEKS) Assessment covers basic algebra to precalculus. Aleks statistics seeks to provide coverage for basic material to prepare you for the advanced technical course at the college or university level. 

So, what are the topics you’ll expect to find? Let’s review some below. 

Arithmetic Review 

The foundational subject in mathematics is arithmetic, which covers operations with numbers. These include multiplication, division, addition, and subtraction. One of the key areas of mathematics, arithmetic, serves as the cornerstone for students studying the topic of mathematics.

Although the topic encompasses many additional modified operations, addition, subtraction, division, and multiplication are the basic operations under arithmetic. A series of integers called an arithmetic sequence has a constant difference between each term.

One area of mathematics called arithmetic works with various sorts of numbers, such as odd numbers, whole numbers, and even numbers. Its fundamental operations include addition, subtraction, multiplication, and division.

Algebra Review 

In the mathematical discipline of algebra, numbers are represented by symbols in formulae and equations. Mathematicians may create formulae and solve problems more quickly if they comprehend these symbols, how they interact, and how they provide equations structure.

Elementary algebra and abstract algebra are the two subfields of algebra. The algebraic symbols and equations taught in primary school are considered elementary algebra. The study of algebraic structures like vector spaces and groups is a part of abstract algebra, often known as contemporary algebra.

Slope and Lines 

A line’s slope in mathematics is defined as the ratio of the change in the y coordinate to the change in the x coordinate. A line’s slope often indicates the steepness and direction of the line.

In arithmetic, we frequently want to quantify the steepness. Slopes B and C are higher than slope A. While slope A is just four units high, they are both seven units high. Therefore, it would seem that height and steepness are related.

Collecting and Displaying Data 

Data management is acquiring and storing information before presenting it in a way others can use and understand. We depict the data processing process as a cycle because we could have new research questions after we have compiled, visualized, and analyzed the findings. The cycle will then need to be repeated.

Organizing data once gathered involves grouping the information in a way that makes it simpler to read. Using tallies and frequency tables, we may arrange data. Data must be summarized once it has been gathered and organized. By summarizing the data, we may quickly identify the key insights the data has provided.

When we summarize data, we employ various techniques to highlight what the entire body of data has informed us. The mean, mode, and median are numerical values obtained using these techniques. We have gathered, organized, and summarized the data until this point. To communicate our research findings with others, we must now figure out how to present the data.

Describing Data 

Since “descriptive” has the same root as “describe,” it usually refers to describing something. Using approaches like graphical representations, measures of central tendency, and measures of variability, descriptive statistics effectively represent the data. It provides a meaningful data summary, allowing us to conclude it.

Both quantitative and qualitative data types are possible. Quantitative information is presented in numeric form, which can be discrete and only accept finite numerical values, or continuous, which also accepts fractional values. For instance, a discrete variable is the number of females in a class since it can only take finite values, but a continuous variable is the price of a product.

Counting and Basic Probability 

A probability is a numerical representation of the possibility or chance that a specific event will occur. Proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.

A probability of 0 means there is no possibility of an event, but a probability of 1 means the event will happen. A probability of 0.45 (45%) means that there are 45 out of 100 possibilities that the event will occur.
