1 Histogram Tab Per the survey, the data were grouped into 5 different categories (bins), as such the frequency distribution was run for each category and per specific provider for the ease of interpretation of the data presented. The histogram table beside it depicts the graphic distribution of all observations in a quantitative data set to better understand the distribution of the dataset. The height of the column shows the frequency for a specific range of values. AT&T: Results show that categories 1 and 5 are the smallest and that the majority of the data falls into category 3 and 4, which in total represent 73% of the total AT&T users surveyed. Verizon: 50% of the population is in the category 3, and categories 4 and 5 are distributed equally having 20% in each bin. No users were identified in in the category 1. Sprint: In comparison to AT&T and Verizon, where data in distributed among different …show more content…
There are a few noticeable outliers, which could lead to a significant differences in the analysis of the results. Therefore those instances need to be investigated further to determine how much of the effect they might have on the overall results. 5 Pie Tab A pie chart divides data into sectors to illustrate the proportion of each category within the population. In our case in 2000 the majority of occupations were represented by Scientists (31%), second place shared Mathematical/Computer Scientists and Computer Specialists with 24% in each category and the least represented category was the Mathematical Scientists. In 2010 Scientist still hold the largest share of the total population (32%), with similar results for Mathematical/Computer Scientists and Computer Specialists, however, there was a drop in the Life Scientist, Engineers and Social Scientists categories. 6 Line
