What is a data display in which the frequencies of different values are represented by small round points?

Answer to the following question is Dot plot

Explanation:

A dot chart is also called the dot plot it is the type of a simple histogram like chart that is used in the statistic for relatively the small data set where the values fall into the number of a discrete bin.  

To draw the dot plots, count the numbers of data points falling in each of the bins and draw the stacks of dot that numbers high for each of the bins.

One way to solve this problem is if you clear up some storage space. On my computer things were running very slowly and I checked my storage and it was beyond full. Another way would be to clean up your hard drive, run some virus and malware scans as your computer may have some viruses that would be slowing it down. Some others ideas are to download more memory on your computer, install a faster hard drive, and reinstall or upgrade your operating system. I hope this helps!!
