Satisfactory Essays

When it comes to smartphones, people make choice which smartphones is suitable for them and, sometimes people look at who gives more feature. In this project, the populations is representing are Population 1 which is all iPhone users in Montclair State University and, Population 2 is all Samsung users in Montclair State University. The quantitative variable I will using is cost. I will compare this two major population iPhone vs. Samsung. Also, the I will use this variable cost because I will be comparing iPhone models like five se, six s, six s plus, seven and, seven plus to Samsung s six, s six edge, s seven edge, note five and note seven. This data will show; how much people spend money on this device.
When I started to look and gather …show more content…

The median for both histograms and box plots show that the median is 749 dollars for iPhone user and 729.99 dollars for Samsung users. This shows the difference relationship between two users. People who using iPhone pay extra 20 dollars for phone, where Samsung users pay less but, for different models. Based on visualizng histograms I think there are more Samsung users than iPhone because Maximum for Samsung is 849.99 dollars.
The data that I have is accurate because by looking at the histogram the graphs are perfectly skewed and, the data make sense, if I compare the data to the median and the IQR. And to find IQR subtract Quartile 3 from Quartile 1. The purpose of using mean value to see if the graph is symmetric or not but, in my case I do not have symmetrical graph or Boxplot, because it is sensitive to outliers. I choose to use the IQR instead of the standard deviation because it shows what is below the 1st quartile and above the 3rd quartile. To summarize, median and IQR are the best option because they resistant to outliers.
In resolution, the distribution of the data shows that iPhone users have lower cost to Samsung Users because the differences between to users is
