Comparing mean, median ,mode

Mean = $\dfrac{\text{Sum of the set}}{\text{Number of elements in the set}}$ = $\dfrac{(3+4+6+7+7+7+8+9+9+10)}{10}$ = $\dfrac{70}{10}$ = $\boxed{7}$

---

Median = The middle value of a set of linear values, which separates the higher and lower halves. But where there is an even number of elements in the set, the Mean of the two middle-most values is used = $(3,4,6,7,\color{#D61F06}7\color{#333333},\color{#D61F06}7\color{#333333},8,9,9,10)$ = $\dfrac{\color{#D61F06}7\color{#333333}+\color{#D61F06}7}{2}$ = $\boxed{7}$

---

Mode = The value that appears most often = $(3,4,6,\color{#D61F06}7\color{#333333},\color{#D61F06}7\color{#333333},\color{#D61F06}7\color{#333333},8,9,9,10)$ = $\boxed{7}$
