Question 1 of 6
1. Question
Find the mean`1` `3` `4` `5` `5` `6` `7` `7` `12` Round your answer to one decimal place- `\text(Mean )=` (5.6)
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.$$ \color{#00880a}{{\small\sum} x} $$ `=` `1+3+4+5+5+6+7+7+12` `=` `50` Evaluate 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 `=` $$\frac{\color{#00880a}{50}}{\color{#e85e00}{9}}$$ There are `9` given values `=` `5.6` Rounded to one decimal place `\text(Mean)=5.6` -
Question 2 of 6
2. Question
Find the mode`1` `1` `2` `2` `2` `2` `2` `3` `3` `4` `4` - `\text(Mode )=` (2)
Correct
Keep Going!
Incorrect
The mode of a data set is the value with the highest frequencyWe need to identify the value that appeared most from the data set.`1` `1` `2` `2` `2` `2` `2` `3` `3` `4` `4` We can see that the value `2` occured five times, and is the most frequent value of the data set.Therefore, the mode for this data set is `2``\text(Mode)=2` -
Question 3 of 6
3. Question
Find the median`5` `8` `7` `8` `4` `6` `3` `6` - `\text(Median )=` (6)
Hint

Well Done!
Incorrect
The median is the middle value of a data set.If there are two middle values on a data set, we get their sum and halve it to get the median.First, arrange the values of the data set in ascending order`3` `4` `5` `6` `6` `7` `8` `8` We can see that the values `6` and `6` are the middle values of the data set.To find the median, we add the two middle values and divide it by `2``\text(Median)` `=` `(6+6)/2` `=` `12/2` `=` `6` `\text(Median)=6` -
Question 4 of 6
4. Question
Find the median`5` `3` `3` `7` `9` `11` `6` `5` `5` `5` `6` `5` `9` `7` `9` `3` - `\text(Median )=` (5.5)
Correct
Great Work!

Question 5 of 6
5. Question
Find the range`4` `3` `-5` `7` `8` `6` - `\text(Range )=` (13)
Hint
Help VideoCorrect
Correct!
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.`\text(Highest Score)` `=` `8` `\text(Lowest Score)` `=` `-5` Finally, subtract the lowest score from the highest score to get the range`\text(Range)` `=` `\text(Highest Score)``-``\text(Lowest Score)` Finding the range `=` `8``-(``-5``)` Substitute values `=` `13` Evaluate `\text(Range)=13` -
Question 6 of 6
6. Question
Find the range`36` `27` `30.1` `35.7` `32.1` `47.3` `28.3` `25.3` `36` `43.9` `39.7` `26.3` `25.1` `19` `27.4` `36.1` - `\text(Range )=` (28.3)
Correct
