Pupil outcome: I can explain why the heating effect of the Sun is greater at midday than at sunrise. Key learning points: - Heating a surface from directly overhead is more effective than heating a surface at a different angle. - When...

Pupil outcome: I can plot and interpret data points on scatter graphs. Key learning points: - Data is given as pairs of values. - The independent variable is placed on the horizontal axis. - Placing the independent variable on the other...

How can you tell if a relation is a function?

How to solve word problems using point-slope form of a line. Typically, students are very comfortable using slope-intercept form of an equation, but we rarely see examples where using point-slope form is the most efficient. In this...

See how the definitions of domain and range apply to real-world situations.

Algebra 1 STAAR/EOC released test questions. These are practice problems meant to help you review and practice as you prepare for your STAAR test / EOC test for Algebra 1 (Texas). Readiness standard A2A - determine the domain and range...

Now that we know what differential equations are, we have to learn how to classify them. We have to know whether a DE is ordinary or partial, linear or nonlinear, homogenous or nonhomogenous, autonomous or nonautonomous. We have to be...

This Video Explains Marketing - What is Experimental Research

A sensitivity analysis is used to test how variations in specific factors affect an outcome. The assumptions employed as part of the situational analysis are generally based on historical information, hypotheical contexts, and constancy

This video explores the concept of cost behavior and its relevance to managerial judgment. The video introduces two common methods for assessing cost changes: the high-low method and regression analysis. The video emphasizes that...

This is a video about linear regression and how when undertaking multiple regression analysis, we need to take into account the possibility of variables that interact and effect modifiers. Interaction and effect modifiers are important...

This video explains the linear regression model.<br<br/>/>

This clip is from the chapter "Linear Regression Analysis" of the series "R Programming for Statistics and Data Science".This section explains linear regression analysis.

In natural experiments circumstances present researchers with the perfect opportunity to test the effect of one variable on another in ways that just couldn't be done in a laboratory. This film looks at some natural experiments in...

Lineweaver-Burk Equation Theory and Derivation

Simple linear regression models using R programming doesn't need to be scary. This video will take you through the basics of how to interpret linear regression results and the code needed to do the regression models. If you are learning...

From the section: Simple Classification Tree. This section we will expand our knowledge of regression Decision tree to classification trees, we will also learn how to create a classification tree in Python.

This video is a lecture presentation on investigating anaerobic respiration in yeast. The presenter explains a general method for investigating factors that might affect the rate of anaerobic respiration in yeast by monitoring the rate...

This is a lecture presentation on rates of reaction experiments. The presenter discusses the concept of the rate of a reaction and how it can be measured. The focus of the experiment is on investigating the relationship between the...

n this live-action program viewers will learn experiments are a key step in the scientific process and to conduct a successful experiment, the scientist must know how to design, plan, and execute an experiment. Students will come to...

The archery contest has a long list of rules, but Chelsea the Cheater keeps breaking them! How does this affect the outcome (conclusion) of the competition? This lesson will introduce the concept of validity and examine the importance...

What is the difference between DIRECTIONAL and NON-DIRECTIONAL HYPOTHESES? What even is a HYPOTHESIS? Every experiment starts with a hypothesis - predicting the outcome of the experiment. Directional hypotheses predict the direction of a...

The archery contest has a long list of rules, but Chelsea the Cheater keeps breaking them! How does this affect the outcome (conclusion) of the competition? This lesson will begin our analysis of validity by examining the importance of...
