Mean, mode, median? What's the difference? How do you find them? The teacher focuses on explaining median in this video. She gives a good explanation and shows how to order a data set to find the median number. This given data set has an...

Scatter plots refer to a graph of given data. Scatter plots offer a way to look at information and allows the observer to analyze and interpret possible meanings and trends of the given data. Predictions can often be made based on the...

What does it mean when a scatter plot graph shows that there is no correlation? Does it have something to do with the slope of the line of fit? Yes, it certainly does have to do with the line of fit. If the slope of the line is zero,...

With a well organized and clear explanation, this video will help students better understand independent and dependent events. Clear visual examples are provided and fully explaining.

Introduce your class to the value and practical applications of statistics. This is the first unit in a series completely focused on describing the three main activities involved with statistics. This video provides an overview of data...

What's Sal's take on the economic stimulus package? He breaks down some government-provided statistics to determine the total price per job created.

You already know that the mode of a data set is the number that occurs most often in the set. But what if all of the numbers in the set occur the same number of times? I could tell you the answer, but I think you should watch the video.

The data sample comes from the number of glasses of water consumed each day by 15 students. You are trying to find minimum, maximum, median, and quartile from this data set. Minimum is the smallest number that occurs, while maximum is...

So you have a data set and you want a visual diagram to help you analyze the data. Not sure how to draw it? The instructor illustrates four different ways to look at a frequency table: two tally tables, one line graph, and one bar graph....

Mode, the number that occurs most often. A data set could have one mode, no modes, or multiple modes. The teacher explains these variations and even gives some example of non-numerical data and how to figure out the mode.

So you've got some x-values and some y-values and you want to make a scatter plot. First thing is to make a table for your x and y values. Then make ordered pairs and you can plot them.

Looking for the range of a set of numbers? Well, that means you are looking for the difference between the largest value and the smallest value. So first, write the numbers in order from least to greatest. Then identify the largest value...

The teacher gives a very thorough explanation of numerical or quantitative data being anything where the answer to a question would be a number. Whereas any other answer might be considered categorical. She shows several different ways...

Mean, mode, median? What's the difference? How do you find them? The teacher focuses on explaining median in this video. She gives a good explanation and shows several examples using different sets of numbers.

Mode, the number that occurs most often. A data set could have one mode, no modes, or multiple modes. The teacher explains these variations and even gives some example of non-numerical data and how to figure out the mode.

What is the mode of a data set? Mean, mode, median. Get confused in remembering which is which? Mode is the number that appears the most times in a data set. So given a data set, arrange the numbers in numerical value from least to...

Average, mean, average, mean. They are the same thing. So just use the formula for finding the average of a set of numbers to get the mean. Add up the value of the terms and then divide by the number of terms in the data set. There's the...

So you have a data set and you want a visual diagram to help you analyze the data. Not sure how to draw it? The instructor illustrates four different ways to look at a frequency table: two tally tables, one line graph, and one bar graph....

So you have a data set and you rewrite the numbers in order from least to greatest. You find that there are two number values that occur twice in the set. Oh no, mode means the number that occurs the most times in a set. Now what do you...

The teacher gives a very thorough explanation of numerical or quantitative data being anything where the answer to a question would be a number. Whereas any other answer might be considered categorical. She shows several different ways...

The data sample comes from the number of glasses of water consumed each day by 15 students. You are trying to find minimum, maximum, median, and quartile from this data set. Minimum is the smallest number that occurs, while maximum is...

If the y-value decreases as the x-value increases then you have a negative correlation. Meaning that the line-of-fit has a negative slope.

What is a line-of-fit? Given a data set, plot the ordered pairs on a graph. It looks like a scatter plot. Now estimate, and draw a line that best fits what the data represents. That is your line-of-fit.

Kurtosis is a measure of weather data is peaked or flat. It will be displayed as a curve with long tails and a high peek. Each of the various kurtosis curves of distribution are describes and explained.
