Published in Paul W. Ross, The Handbook of Software for Engineers and Scientists, 2018
Stata (pronounce it to rhyme with data) is an interactive software system for statistics, graphics, and data management. Stata is available for Windows™, DOS, Macintosh, and Unix computers and is essentially the same program in all four environments.

The exploratory research design was employed because it allowed the researchers to explain, analyse and report conditions that exist in the study area. This design was also applicable as it sought to gather relevant information on the existing status of the phenomena and explained it as existed in reference to variables in a situation (Mugenda and Mugenda 2003). Primary data was collected from 400 households randomly selected from six (6) communities from Cape Coast North and South Metropolis. The study employed simple random sampling to select six (6) communities within the Cape Coast Metropolis (thus, two each from rural, peri-urban and urban communities). Proportional sampling was employed to select the number of household from each of the six (6) communities (Table 1) and finally, the convenience sampling was used to identify the household heads as they constituted the unit of analysis for the study. Household heads were the primary respondents but, in few cases, persons 18 years and older, in the absence of the household head were conveniently sampled in place of the household heads. Primary data were collected using the interview schedule. Microsoft Excel and SPSS were used to process the data whiles SPSS and STATA were used in analysing the data. Tables and pie charts were used in presenting the results. Issues of ethics were adhered to including informed consent, anonymity and confidentiality.
Assessing the Nutrition and Family Usage of a Backpack Food Program

The survey instrument consisted of both open-ended and multiple-choice questions. Survey results were sorted and tabulated to present foods that the respondents found to be most liked, least liked, most desired to be added to the program, and those that go uneaten or are thrown away (open-ended). Descriptive indicators were also tabulated to show the percentages of families responding that they shared food across the family, threw food away, changed buying behavior, knew of others that did not sign up for the program, and saw effects on the student’s grades, attendance, and health. Due to the number of open-ended questions in the instrument, the preliminary/pilot nature of the assessment, and specific group of respondents, statistical analysis was limited to descriptive means for categorical questions (e.g. the percentage of families that threw away food) and counts of answers for open-ended questions (e.g. the number of families that liked a given food item the most). Data analysis and presentation was performed using a combination of STATA14 and Microsoft Excel.15
Cluster analysis of the spatial distribution of pedestrian deaths and injuries by parishes in Kampala city, Uganda
Published in International Journal of Injury Control and Safety Promotion, 2023

All the crashes registered involving pedestrians within the study period were either fatal or serious with none reported as a minor crash. Statistics of the pedestrians involved in the crash by age and gender, crash statistics by time and date of occurrence as well as trends by year were computed as percentages. Being involved in a crash does not necessarily mean resulting in death or serious injury. Absolute and relative measures of pedestrian deaths and injuries were computed. However, we did not have information on how many of those involved in the crashes had died or were injured from the TSDs, and abstracting that information from the TARs would have been time-consuming. Based on the definition of the traffic police as a fatal crash being one that involved at least one death, we approximated the number of pedestrians killed assuming a minimum of 1 death for each fatal crash reported. To approximate the number of pedestrians injured from serious crashes, we only considered crashes involving 1 pedestrian. Microsoft Excel 2016 and STATA SE version 14 software (Stata, 2015) were utilized for this computation. Since the population data was from the 2014 census (the last census conducted in Uganda) while the crash data was from 2015 to 2019; the estimated population was calculated using the estimated growth rate of Kampala by 4.03% (Kampala Capital City Authority, 2019; Uganda Bureau of Statistics, 2014), to obtain an average population for 2015 to 2019 assuming a constant growth rate. Using the average 5-year population, fatal injury rates and serious injury rates per 100,000 population were then calculated for each parish.
