For my final project in an advanced methods in Excel class I analyzed a dataset that was collected through user experience research of 3D thematic maps intended for visually impaired students.
First, I analyzed the demographics of the participants to see if the sample group was skewed, and if there were any trends in their responses based on their demographics. I later found there to be little to no trends based on participant demographics.
The graphs below display my findings.
I then examined and organized the data collected from the answers of the questions that each of the participants were asked to assess the effectiveness of the product.
​
The results revealed that question 6 gave the participants significantly more trouble than any of the other questions. Question 6 read as follows: "How many residents does Australia have?"
This highlighted that the feature for discovering number of residents in a country, was less intuitive compared to map features.
​
The graphs below display this finding.
Lastly, I calculated each participant's System Usability Scale (SUS) score from a dataset that included each participant’s rating response to a set of 10 statements that were derived from the System Usability Scale (SUS).
This revealed that most participants gave the maps a passing grade (>68) and deemed it a usable product. The average SUS score came out to be 70.88, earning it an overall usability grade of "B" and a "Good" rating.
​
I also calculated the SUS score for each question in the SUS survey to find specific areas of improvement for the product.
Question 4, which states, "I think that I would need the support of a skilled person to be able to use this map/these maps,” had the lowest score. This suggests that improvements could be made to how intuitive the maps are, to make them easier to understand for new users.
