In this short video we will answer a standardized test question by rewriting a value in scientific notation to standard form.

Today we're going to walk through a couple of statistical approaches to answer the question: "is coffee from the local cafe, Caf-fiend, better than that other cafe, The Blend Den?" We'll build a two sample t-test which will tell us how...

Test statistics allow us to quantify how close things are to our expectations or theories. Instead of going on our gut feelings, they allow us to add a little mathematical rigor when asking the question: “Is this random… or real?” Today,...

Today we're going to begin our three-part unit on p-values. In this episode we'll talk about Null Hypothesis Significance Testing (or NHST) which is a framework for comparing two sets of information. In NHST we assume that there is no...

This video lesson provides guided practice to prepare for a Grade 7 Common Core Mathematics cumulative assessment. The questions that are presented and modeled are the released 2018 MCAS Session B questions. A calculator IS permitted...

This video explains how to convert scientific notation to standard notation in a clear and concise way. By breaking down the steps and providing examples, students can easily understand and apply this concept to solve standardized math...

In this short video we will learn the easy way to write a number phrase in standard form as we answer a standardized math test question. We will begin by understanding that the word "and" represents the decimal point when a number is...

In this video, we learn how to convert a number written in scientific notation to standard notation. The teacher explains the process step-by-step and shows an example of converting 8.25 * 10 to the 5th to 825,000.

In this video, the teacher explains how to convert a number from scientific notation to standard notation, using a specific example. They provide step-by-step instructions and highlight important concepts to help students master math...

In this video, the teacher explains how to use the vertical line test to determine if a graph is a function or not. The viewer is presented with four graphs and asked to identify which one is not a function. The teacher demonstrates...

The video is a lecture on how to test for outliers in datasets and provides three methods for identifying them. The instructor explains the importance of identifying outliers to ensure the validity of data and outlines the three methods:...

👉 Learn how to graph linear inequalities. Linear inequalities are graphed the same way as linear equations, the only difference being that one side of the line that satisfies the inequality is shaded. Also broken line (dashes) is used...

In this shorts video we will discuss scientific notation & standard form. We will be given a value written in scientific notation. We will understand that it is in scientific notation since there is one significant digit to the left of...

In this short video we will determine the quotient to solve a problem. I will read a problem, ask you to pause and solve, and return to view the solution. We will identify that we are tasked with determining the quotient using the...

In this short video we will answer a standardized test question using order of operations. We will rewrite subtraction to add the opposite. We will learn that we can add repeated addition in any order. We will add the positive values...

👉 Learn how to graph linear inequalities written in standard form. Linear inequalities are graphed the same way as linear equations, the only difference being that one side of the line that satisfies the inequality is shaded. Also broken...

👉 Learn how to graph linear inequalities written in standard form. Linear inequalities are graphed the same way as linear equations, the only difference being that one side of the line that satisfies the inequality is shaded. Also broken...

👉 Learn how to use the Rational Zero Test on Polynomial expression. Rational Zero Test or Rational Root test provide us with a list of all possible real Zeros in polynomial expression. Rational Zero Test can be helpful to find all the...
