Question 1

The points scored on a math quiz were:19, 25 , 21 , 22, 20, 26, 26, 17Find the mean_____Median_______Mode______ Help me Please.

Question 2

Answer:

$\begin{gathered} \text{ mean=22} \\ \text{medium}=21.5 \\ \text{ mode=26} \end{gathered}$

Step-by-step explanation:

Rewriting the given data in ascending order;

Calculating the mean;

$\begin{gathered} \operatorname{mean}=\frac{\text{ sum of data}}{\text{ number of data}}=(17+19+20+21+22+25+26+26)/(8)=(176)/(8) \\ \operatorname{mean}=22 \end{gathered}$

Calculating the median;

$\begin{gathered} \operatorname{median}=\text{the middle number when arranged in ascending order.} \\ \operatorname{median}=(21+22)/(2)=(43)/(2)=21.5 \end{gathered}$

Calculating the mode;

$\begin{gathered} \text{ mode= most occurring number/number with the highest frequency mode } \\ \text{ mode= 26} \end{gathered}$

Therefore, we have;

$\begin{gathered} \text{ mean=22} \\ \text{medium}=21.5 \\ \text{ mode=26} \end{gathered}$
