A line plot of a data set shows the various numbers of the data set along the x axis as per a convenient scale.
The Mean is you add all the number together and divide it by the number if numbers there are. To find the median count the dots from left to right until you find the middle value. The median is the average value from a set of data and is shown by the line that divides the box into two parts. In this video we will learn how to calculate the mean median mode and range of data from dot plots.
