Great Work!
Incorrect
A dot plot is a number line that contains all possible scores from a data set and uses dots to represent frequency.First, find the highest and the lowest score.`\text(Highest Score)` `=` `14` `\text(Lowest Score)` `=` `6` Create a number line with with ascending values from the lowest to highest scores
Next, read across the data while placing a dot above the corresponding score.`8` `11` `12` `11` `11` `10` `11` `9` `8` `12` `14` `13` `10` `6` `10` `14` `11` `10` `9` `11` 
Continue doing this until all scores are accounted for.
To check, count the total dots and make sure it is equal to the number of given scores, which is `20`.

Question 5 of 11
5. Question
Find the mode of the dot plot below.
- `\text(Mode )=` (11)
Hint
Help VideoCorrect
Excellent!
Incorrect
The mode of a data set is the value with the highest frequencyThe mode of a dot plot is represented by the score with the most dots.
We can see that the score `11` has `6` dots, and is the most frequent score on the dot plot.Therefore, the mode for this data set is `11``\text(Mode)=11` -
Question 6 of 11
6. Question
Find the mode of the dot plot below.
- `\text(Mode )=` (66)
Correct
Great Work!
Incorrect
The mode of a data set is the value with the highest frequencyThe mode of a dot plot is represented by the score with the most dots.
We can see that the score `66` has `3` dots, and is the most frequent score on the dot plot.Therefore, the mode for this data set is `66``\text(Mode)=66` -
Question 7 of 11
7. Question
The scores for a game are represented on the dot plot below. Find the median.
- `\text(Median )=` (7)
Hint
Help VideoCorrect
Fantastic!
Incorrect
The median is the middle value in an ordered set of data.Take note that there is a total of `19` scores on the dot plot, which is an odd number.Therefore, the median of the data set will be the score on the `10th` position.
`\text(Median)=7` -
Question 8 of 11
8. Question
Find the median of the dot plot below.
- `\text(Median )=` (51)
Correct
Nice Job!
Incorrect
The median is the middle value in an ordered set of data.Take note that there is a total of `10` scores on the dot plot, which is an even number.Therefore, the median of the data set will be the average of the scores on the `5th` and `6th` positions.
`\text(Median)` `=` `(49+53)/2` `=` `102/2` `=` `51` `\text(Median)=51` -
Question 9 of 11
9. Question
The scores for a game are represented on the dot plot below. Find the mean.
Round your answer to two decimal places- `\text(Mean )=` (7.53)
Hint
Help VideoCorrect
Fantastic!
Incorrect
Mean Formula
$$\text{Mean}=\frac{\color{#00880a}{\sum x}}{\color{#e85e00}{N}}$$Remember
$$ \color{#00880a}{{\small\sum} x} $$ is the sum of all the given values.`N` is the number of given values.First, solve for the sum of the given values.The number of dots on a value indicates how many times a score occurs on the data set.$$ \color{#00880a}{{\small\sum} x} $$ `=` `3+(5xx2)+6+(7xx6)+(8xx4)` `+(9xx2)+10+(11xx2)` `=` `143` Next, divide the sum of all values $$( \color{#00880a}{{\small\sum} x} )$$ by the number of values (`N`).`\text(Mean)` `=` $$\frac{\color{#00880a}{{\small\sum} x}}{\color{#e85e00}{N}}$$ Finding the mean `=` $$\frac{\color{#00880a}{143}}{\color{#e85e00}{19}}$$ There are `19` given values `=` `7.53` Rounded to two decimal places `\text(Mean)=7.53` -

10. Question
Find the mean of the dot plot below.
Round your answer to two decimal places- `\text(Mean )=` (46.69)
Correct

Question 11 of 11
11. Question
Find the outlier of the dot plot below.
- `\text(Outlier )=` (6)
Hint
Help VideoCorrect
Exceptional!
Incorrect
The outlier is the score that is separated from the main body of data.We can see on the dot plot that the value `6` is separated from the rest of the dots
Therefore, the outlier of this data set is `6``\text(Outlier)=6`
