Family Income vs. Academic Performance
What is the project about? Why is it important?
We are exploring how a student's family income level affects their academic performance (school grades).
This topic relates to equity in education, not all students have the same opportunities.
Students from lower-income families often:
Have less access to tutoring or extra help
May lack technology like laptops or internet
Might not have a quiet place to study
Experience poor sleep or nutrition
These factors can affect grades and overall school success.
We want to investigate if there’s a statistical link between income and performance.
What are the two variables you’re comparing?
Variable 1: Family Income
Collected as a range:
Less than $30,000
$30,000 – $59,999
$60,000 – $99,999
$100,000 and above
Participants choose a range instead of reporting exact income for privacy.
Variable 2: Academic Performance
Student’s self-reported average grade (%)
This can be from their most recent report card or current average.
Both are quantitative variables, suitable for scatter plots and correlation analysis.
What are you trying to find out? What do you expect?
Research Question:
Does family income level affect a student’s average grade?
Hypothesis:
Students from higher-income families tend to have higher academic averages than students from lower-income families.
Why?
Families with more income can afford more educational support (e.g., private tutoring, books, better school supplies).
Higher income often means less stress and more stable living environments, which can help students focus.
How will you get your data? Who will you ask?
We will create a Google Form survey with 2 key questions:
What is your estimated family income range? (select from options)
What is your current average grade (%)?
Data will be:
Anonymous
Collect the data from students in our school.
Voluntary participation
Our target is to collect at least 200 responses to ensure our sample size is large enough for valid analysis.
We will ensure responses are private and won’t ask for names or identifying information.
How will you analyze the data? What graph will you use?
We will organize the data in a Google Sheet or Excel.
We will group students based on the income range they selected.
For each income group, we will calculate the average grade.
Then, we will create a bar graph to compare the average grades across different income levels.
Example:
Bar 1: Students with income under $30k → Average Grade: 72%
Bar 2: Income $30k–$60k → Average Grade: 75%
Bar 3: Income $60k–$100k → Average Grade: 80%
This will help us visually see if higher income levels are linked to higher grades.
Why does this matter beyond just math?
This project highlights the inequities in our education system.
Students from lower-income families may not do poorly because they’re less capable, they often just don’t have the same resources.
It shows how systemic issues (like poverty and access) can create academic gaps.
Results can:
Raise awareness among students, teachers, and administrators
Encourage schools to offer more support to low-income students
Contribute to the discussion about fairness in education
