Question 1 of 9
1. Question
Create a dot plot using the data set below.`3` `3` `3` `3` `4` `5` `5` `5` `5` `5` `7` Correct
Well Done!
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)` `=` `7` `\text(Lowest Score)` `=` `3` 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.`3` `3` `3` `3` `4` `5` `5` `5` `5` `5` `7` 
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 `11`.

Question 4 of 9
4. Question
The scores for a game are represented on the dot plot below. Find the mode.
- `\text(Mode )=` (7)
Hint
Help VideoCorrect
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 `7` has `6` dots, and is the most frequent score on the dot plot.Therefore, the mode for this data set is `7``\text(Mode)=7` -
Question 5 of 9
5. Question
Find the mode of the dot plot below.
- `\text(Mode )=` (7)
Correct
Nice Job!

Question 6 of 9
6. Question
The scores for a game are represented on the dot plot below. Find the range.
- `\text(Range )=` (8)
Hint
Help VideoCorrect
Keep Going!
Incorrect
Range Formula
`\text(Highest Score)``-``\text(Lowest Score)`Remember
The range of a data set is simply the difference between the largest and smallest values.First, find the highest and the lowest score on the dot plot. Both points must have dots.
`\text(Highest Score)` `=` `11` `\text(Lowest Score)` `=` `3` Finally, subtract the lowest score from the highest score to get the range`\text(Range)` `=` `\text(Highest Score)``-``\text(Lowest Score)` Finding the range `=` `11``-``3` Substitute values `=` `8` Evaluate `\text(Range)=8` -
Question 7 of 9
7. Question
Find the median of the dot plot below.
- `\text(Median )=` (11)
Hint
Help VideoCorrect
Excellent!
Incorrect
The median is the middle value in an ordered set of data.Take note that there is a total of `20` 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 `10th` and `11th` positions.
`\text(Median)` `=` `(11+11)/2` `=` `22/2` `=` `11` `\text(Median)=11` -
Question 8 of 9
8. Question
Find the median of the dot plot below.
- `\text(Median )=` (15)
Correct
Well Done!
Incorrect
The median is the middle value in an ordered set of data.Take note that there is a total of `17` scores on the dot plot, which is an odd number.Therefore, the median of the data set will be the score on the `9th` position.
`\text(Median)=15` -
Question 9 of 9
9. Question
Find the mean of the dot plot below.
Round your answer to two decimal places- `\text(Mean )=` (2.36)
Correct
Nice Job!
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.$$ \color{#00880a}{{\small\sum} x} $$ `=` `1+(2xx7)+(3xx2)+5` `=` `26` 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 `=` $$\frac{\color{#00880a}{26}}{\color{#e85e00}{11}}$$ There are `11` given values `=` `2.36` Rounded to two decimal places `\text(Mean)=2.36`
