Calculator MVSD Work — A Short Narrative
The calculator sat on the edge of Marisol’s desk like a tiny observatory, its plastic face turned toward the window where late-afternoon light slanted across the city. She had named it MVSD because the initials matched the problem she’d been wrestling with all week: mean, variance, standard deviation. The label made it feel less like a tool and more like a companion that knew secret languages of numbers.
- Find deviations: (10-19)=-9, (20-19)=1, (30-19)=11
- Square: 81, 1, 121
- Multiply by f: 813=243, 15=5, 121*2=242
- Sum = 490
- Sample variance = 490/(10-1) ≈ 54.44

Sum of Squares: $$ 1.44 + 7.84 + 0.64 + 0.04 + 4.84 = \mathbf14.8 $$
Find Standard Deviation ((s) or (\sigma))
Take square root of variance.
