Maria ran an experiment to determine the optimal conditions for growing artichokes. The data below displays the weights of the artichokes she grew (measured in grams).
128.7	131.6	95.6	106.7	111.9
131.6	117.4	115.6	131.6	103.4

What is the mean weight of the artichokes?

mean =

What is the median weight of the artichokes?

median =

What is the mode weight of the artichokes?

mode =

Let's calculate the mean, median, and mode of the artichoke weights.

### Given Data:
128.7, 131.6, 95.6, 106.7, 111.9, 131.6, 117.4, 115.6, 131.6, 103.4

### 1. Mean Weight:
The mean is calculated by summing all the weights and dividing by the number of weights.

\[
\text{Mean} = \frac{128.7 + 131.6 + 95.6 + 106.7 + 111.9 + 131.6 + 117.4 + 115.6 + 131.6 + 103.4}{10}
\]

Let's calculate this:

\[
\text{Mean} = \frac{1174.1}{10} = 117.41 \text{ grams}
\]

### 2. Median Weight:
To find the median, we first need to arrange the data in ascending order:

95.6, 103.4, 106.7, 111.9, 115.6, 117.4, 128.7, 131.6, 131.6, 131.6

Since there are 10 numbers, the median will be the average of the 5th and 6th values:

\[
\text{Median} = \frac{115.6 + 117.4}{2} = 116.5 \text{ grams}
\]

### 3. Mode Weight:
The mode is the value that appears most frequently in the data set. 

Here, 131.6 appears three times, so:

\[
\text{Mode} = 131.6 \text{ grams}
\]

### Final Answers:
- **Mean** = 117.41 grams
- **Median** = 116.5 grams
- **Mode** = 131.6 grams

**Relative Questions:**
1. How would the mean change if one more artichoke weighing 140 grams was added?
2. What is the range of the artichoke weights?
3. How would the median change if the smallest weight was removed?
4. If another weight of 131.6 grams was added, how would that affect the mode?
5. How do outliers affect the mean and median of a data set?

**Tip:** When calculating the median, remember to sort the data first, and for an even number of data points, average the middle two values.
