Interactive practice questions
What is the approximate mean of this data set?
A histogram represents the distribution of scores and their frequencies. The horizontal axis labeled "Score" ranges from $8$8 to $17$17. The vertical axis labeled "Frequency" ranges from $0$0 to $10$10. Both axes are marked at $1$1 unit intervals. The gray-shaded bars represents the frequencies of each scores.
The bar at $8$8 has a height $1$1.
The bar at $9$9 has a height $2$2.
The bar at $10$10 has a height $4$4.
The bar at $11$11 has a height $6$6.
The bar at $12$12 has a height $9$9.
The bar at $13$13 has a height $9$9.
The bar at $14$14 has a height $7$7.
The bar at $15$15 has a height $4$4.
The bar at $16$16 has a height $2$2.
The bar at $17$17 has a height $1$1.
$14.1$14.1
$12.5$12.5
$10.5$10.5
