Today we're going to start our two-part unit on data visualization. Up to this point we've discussed raw data - which are just numbers - but usually it's much more useful to represent this information with charts and graphs. There are...

This video provides an introduction to basic statistical concepts, focusing on the use of bar charts as a visual tool for organizing and understanding data. It explains the components of a bar chart, such as the X and Y axes, and how...

This video is a lecture on pie charts, a type of graph used to visualize data values in a data set. The video explains how to construct a pie chart and derive values from a pre-drawn pie chart. The instructor uses simple examples, such...

This video introduces the concept of bar graphs and explains why they are useful for organizing and displaying data. It covers the different parts of a bar graph and how to interpret the information it presents. By using a basketball...

I want to investigate how population has changed in these cities…but these numbers are just numbers. They don’t mean anything to me. In this video, we are going to discover how great bar graphs are for providing us with a clear visual,...

This video provides an introduction to basic concepts in statistics, focusing on the importance and structure of surveys. It explains that a survey is a series of questions used to gather information or opinions on a specific...

In this video, students learn how to create a picture graph by organizing data and creating a key, title, and labels. The video explains the importance of using the same symbol for each category in the graph and demonstrates how to...

In this video, the teacher explains how to identify and interpret picture graphs. They discuss the use of tally charts to collect data and then create a graph. The teacher also emphasizes the importance of the title, key, table, labels,...

In this video, the teacher explains the concept of shape in data distribution using different types of graphs. They discuss histograms, line plots, and bell curves, and how to interpret the shape of the data based on symmetry and...

Data… Nowadays information is being collected on everything… we have data coming out of our ears. These numbers might be showing us something very meaningful but who can really tell? This is where bar graphs and pie charts come into...

In this lesson, students will learn how to determine if a relation is a function or not. By analyzing information and rules, they will be able to identify functions by looking for unique matches between domain and range elements. They...

This video demonstrates how to interpret the information on a picture graph, including the title, key, category labels, and pictures. By creating a T-chart, students can organize the information and easily reference it to answer...

This video we use a T chart to solve a two-step question about the number of juice boxes in a variety pack. We demonstrate how to organize information from a picture graph and perform multiple operations to arrive at the correct answer....

In this video, the teacher explains how to graph square root functions by creating a T-chart. They demonstrate how to find the square root of perfect square numbers and plot the corresponding coordinates on a graph.

In this video, the teacher explains how to graph a quadratic equation using the axis of symmetry, vertex, and T chart. They use the example of a small roller coaster at a kiddie park, showing how to find the height difference from the...

In this video, the teacher explains how to graph absolute value functions using a T chart. They demonstrate how to find the absolute value of a number and address common misunderstandings. The teacher then applies these concepts to...

This video explains how to represent a situation involving two runners, Mark and Paul, on a coordinate plane. By graphing ordered pairs, we can visually compare their running times and distances. The video demonstrates how to plot...

In this video, students will learn how to find the range of a set of data by using graphs and charts. They will also discover how the range changes when an outlier is removed. The lesson covers the concepts of mean and median, and...

In this video, the teacher shows students how to represent data on a number line by creating a histogram. He explains the concept of bins and intervals, and demonstrates how to label and organize data points in a histogram.

This video explains the concept of correlation and how it can be identified using scatter graphs. It discusses positive correlation, where two variables increase together, and negative correlation, where one variable increases while the...

In this video, students will learn how to choose the best representation for their data by considering the strengths and weaknesses of dot plots, histograms, and box plots. They will understand how dot plots provide a clear picture of...

Find all six trig ratios given a point on the terminal side of theta. In this video we work this common type of problem. We use the Pythagorean Theorem to find "r" (hypotenuse), and then use the given "x" (adjacent) and "y" (opposite) to...
