Example Question #31 : Statistics & Probability
Mr. Sommers wanted to see how much money his students spent on school lunch in a given day. The distribution of this data is shown in the plot provided. Use the information provided in the plot to fill in the blank of the table.
The table shows how far away each data value is from the mean. In order to solve for the missing piece of the table, we first need to solve for the mean:
In order to solve for the mean, we need to add up all of the money spent on lunch, and then divide by the number of addends in our set:
The mean for this data set is
Next, we can subtract the data value from the mean to find the deviation from the mean:
The correct answer is
Example Question #11 : Compare The Measure Of Center And Measure Of Variation: Ccss.Math.Content.6.Sp.A.3
Mr. Sommers wanted to see how much money his students spent on school lunch in a given day. The distribution of this data is shown in the plot provided, with each x representing one student in his class. What is the median amount of money that a student spends on lunch?
In order to solve for median, we need to list all of our data points in order from least to greatest:
Next, we want to find the number, or numbers that are in the middle:
The center of distribution, using the median, is
