Mini Lesson
A statistics project is the moment all the data tools you have practiced come together. You start with a question, gather data, sort it, summarize it with measures like mean, median, mode, and range, and then present what you found. The goal is not to show off charts — it is to answer your question clearly and honestly so an audience walks away knowing what your data says.
The Five Sections of a Stats Report
- Question — one clear sentence stating what you want to find out.
- Method — how you collected the data, your sample size, and any tools you used.
- Data — the raw numbers, tally counts, and the chart you built.
- Findings — the mean, median, mode, range, and any patterns you noticed.
- Conclusion — a one-sentence answer to your original question.
Choosing the Right Chart
- Bar chart — best for comparing CATEGORIES (favorite sports, types of pets).
- Line graph — best for showing CHANGE OVER TIME (temperature each day for a month).
- Pie chart — best for showing PARTS OF A WHOLE (percent of a group by birth month).
- Histogram — best for a NUMERIC DISTRIBUTION (how many players scored in each range).
- Box plot — best for the FIVE-NUMBER SUMMARY (min, Q1, median, Q3, max).
- A wrong chart can hide your story — pick the chart that matches the question.
Working with Your Data
- Always sort the data before reporting median, mode, or range.
- Round numbers to a sensible place (one decimal for averages is usually enough).
- Label every axis on every chart, including units.
- Show your sample size — a finding from 5 people is not the same as one from 50.
- Never delete data points just because they do not match your prediction.
Presenting Your Project
- Start by reading your question to the audience, word for word.
- Walk through the method in three or four sentences, no more.
- Point at the chart while you explain what it shows.
- State each finding (mean, median, mode, range) and what it means in plain English.
- End with the conclusion sentence and invite questions.
Tip: a strong stats project answers ONE question well. Resist the urge to add a second question or a second chart until the first one is rock solid.
