How Do You Find the Mode of a Data Set Where All The Numbers are Different?
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.

How Do You Find the Minimum, Maximum, Quartiles, and Median of a Data Set?
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...

What is a Frequency Table?
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....

What is the Mode of a Data Set?
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.

How Do You Make a Scatter Plot?
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.

How Do You Find the Range of a Data Set?
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...

How Do You Find the Mode of a Data Set?
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...

What is the Mean of a Data Set?
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...

How Do You Find the Mode of a Data Set When There is More Than One Mode?
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...

How Do You Use a Scatter Plot to Find a Line of Fit?
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.
