1. What is a TI-84 Histogram?

A histogram is a graphical display of data using bars of different heights. The TI-84 calculator's histogram plots the distribution of numerical data by dividing it into bins (intervals) and counting how many values fall into each bin.

2. How to Use This Calculator

Step 1: Enter your data values separated by commas or spaces
Step 2: Specify the number of bins (bars) you want in the histogram
Step 3: Optionally set the X-axis range (X-min and X-max)
Step 4: Click "Generate Histogram" to see the frequency distribution

3. Interpreting Histogram Results

Shape: The histogram's shape reveals the data distribution pattern (normal, skewed, uniform, etc.)
Center: The central tendency can be estimated from where values concentrate
Spread: The width shows how spread out the data values are
Outliers: Unusually high or low values may appear as isolated bars

4. Frequently Asked Questions (FAQ)

Q1: How many bins should I use?
A: 5-10 bins work well for most datasets. Too few bins oversimplify, while too many make the pattern hard to see.

Q2: What if my data has outliers?
A: Consider adjusting X-min/X-max to focus on the main data range, or analyze outliers separately.

Q3: How does this compare to STAT PLOT on a TI-84?
A: This calculator mimics the TI-84's histogram function but provides numerical results in addition to visual representation.

Q4: Can I copy the histogram data?
A: Yes, you can copy the frequency table for use in other applications.

Q5: Why is my histogram blank?
A: Check that your data values are numeric and properly separated. Also verify that your X-range includes the data values.
