Case Study 015. Harlem Link Data Suite - School Operations: Step 1
Step 1 - Discovery
To begin the process of creating the data reports, I met with the school’s teachers and administrators. I listened to the concerns they had and the challenges they were facing. I began to form an idea of what information needed to be included in the data reports and what raw data needed to be gathered.

Step 3 - Prep Data
To complete this step, I took the following actions:
I identified exactly what data needed to be displayed.
I identified sources for each of those data points.
I exported that data from school information systems (or requested a data export from an outside source).
I cleaned up and organized the data exports.
I compiled the data into Google Sheets.

Step 5 - Identify Insights
Finally, I could draw some insights from the dataset. Here are the main takeaways:
The dataset consists of 51 rows and 42 columns
The dataset consists of:
student enrollment
school staffing
student demographic information
There are 51 rows and 42 columns in the dataset. None of the rows are blank.
The dataset contains totals per state of the number of students in (2) gender categories and (7) race/ethnicity categories.
2018-19 US public school total enrollments by demographic group are as follows:
25.8 million male students
24.4 million female students
473K American Indian/Alaska Native students
2.6 million Asian or Asian/Pacific Islander students
13.7 million Hispanic students
7.6 million Black students
23.7 million White students
176K Hawaiian Nat./Pacific Isl. students
2 million multiracial students
The states with the highest number of Black public school students are: Florida, Georgia and Texas
The states with the highest number of Hispanic public school students are: California and Texas
The state with the highest number of Asian or Asian/Pacific Islander public school students is California. New York and Texas are a distant second and third.The states with the highest number of American Indian/Alaska Native public school students by far is OklahomaThe state with the highest number of Hawaiian/Pacific Islander public school students by far is HawaiiThe states with the highest number of White public school students are: California and Texas

Step 1 - Discovery
My very first step was to meet with the client and determine what his needs were for the project.
From our conversation, I learned that his goal was to create a visual that:
quickly summarized the survey’s key points of information
could be posted online and shared via his email newsletter
allowed users to filter the data by demographic subgroup (location, age, etc.)
stimulated further discussion amongst members of the community
