Jena is comparing prices of different cell phones. She made a dot plot to show the prices. How can she find the most common price?
A) Find the dot all the way to the right.
B) Find the dot all the way to the left.
C) Find the shortest stack of dots.
D) Find the tallest stack of dots.
Plz help I don't understand.. what and why...thank you.
To find the most common price from the dot plot, Jena can follow these steps:
1) Look at the dot plot and identify the prices of the cell phones that are represented by the dots.
2) If Jena wants to find the most common price, she needs to look for the price that appears most frequently among the dots on the dot plot.
Now, let's go through the answer choices:
A) "Find the dot all the way to the right" - This is not the correct choice because the dot all the way to the right may not necessarily represent the most common price. It only indicates a high-priced phone.
B) "Find the dot all the way to the left" - Similarly, this is not the correct choice because the dot all the way to the left does not indicate the most common price. It only represents a low-priced phone.
C) "Find the shortest stack of dots" - This answer choice is also incorrect. The shortest stack of dots does not indicate the most common price. It simply represents a price category with fewer occurrences.
D) "Find the tallest stack of dots" - This is the correct choice. To find the most common price, Jena needs to look for the stack of dots that is the highest or tallest. The taller the stack of dots, the more frequently that price occurs, making it the most common price.
Therefore, Jena can find the most common price by selecting answer choice D) "Find the tallest stack of dots" on the dot plot.
I think answer D)
This is indeed a confusing question, but I'm assuming the plot has price on the X (horizontal) axis and cell phone brand on the Y (vertical) axis. You can try sketching it out to understand...
Let's say there is a value $90 for price. If brand X1 is that price, she puts a dot there. If brand X2 is also that price, she puts a dot corresponding to the coordinate ($90, X2), which shows up above the dot for the other brand at the same price. Then the taller stack of dots means that more cell phones have that price.
