Two-Way Frequency Tables

Level {{step}}/5

Drag to Sort

Organize the space crew into the Two-Way Table based on their species and role.

All sorted!

	🚀 Pilots	🔧 Mechanics
👽 Aliens	{{ getEmoji(item.type) }}	{{ getEmoji(item.type) }}
🤖 Robots	{{ getEmoji(item.type) }}	{{ getEmoji(item.type) }}

Tap to Sum

Find the Marginal Frequencies by adding the rows and columns to find the totals.

	🚀 Pilots	🔧 Mechanics	Total (Row)
👽 Aliens	{{ data.alienPilot }}	{{ data.alienMech }}	- {{ s2UserTotals.r1 }} +
🤖 Robots	{{ data.robotPilot }}	{{ data.robotMech }}	- {{ s2UserTotals.r2 }} +
Total (Col)	- {{ s2UserTotals.c1 }} +	- {{ s2UserTotals.c2 }} +	- {{ s2UserTotals.grand }} +

Slide to Match

Find the Joint Relative Frequency (Probability).
What is the probability of selecting a random crew member who is a {{ s3Question.name }}?

	Pilots	Mechanics	Total
Aliens	{{ data.alienPilot }}	{{ data.alienMech }}	{{ data.r1 }}
Robots	{{ data.robotPilot }}	{{ data.robotMech }}	{{ data.r2 }}
Total	{{ data.c1 }}	{{ data.c2 }}	{{ data.total }}

Probability =

0 Grand Total: {{data.total}}

check_circle Perfect Match!

Tap to Isolate

Find the Conditional Relative Frequency.
Step 1: Tap the {{ s4Condition.name }} header to isolate that group. Step 2: Inside that group, tap the cell for {{ s4Target.name }}. Great job!

	🚀 Pilots	🔧 Mechanics	Total
👽 Aliens	{{ data.alienPilot }}	{{ data.alienMech }}	{{ data.r1 }}
🤖 Robots	{{ data.robotPilot }}	{{ data.robotMech }}	{{ data.r2 }}
Total	{{ data.c1 }}	{{ data.c2 }}	{{ data.total }}

Probability of {{ s4Target.name }} given {{ s4Condition.name }}:
