The line plot shows the amount of salt needed for an egg to float in water, with data points ranging from 7.0 to 7.5 grams. The distribution appears to be slightly skewed to the left, meaning most data points are concentrated on the higher end (7.3 to 7.5 grams), with fewer points on the lower end (7.0 to 7.2 grams).

### Sentence Completion:
1. **The distribution of the amount of salt needed is best described as** skewed to the left.
2. **So, the** median **is a more appropriate measure of center than the** mean.
3. **The** interquartile range (IQR) **is a more appropriate measure of variation than the** standard deviation.

### Explanation:
- **Skewness** indicates the distribution's tail direction; since it's left-skewed, the tail is on the left.
- **Median and IQR** are preferred measures when distributions are skewed, as they are less affected by outliers compared to mean and standard deviation.

### Related Questions:
1. How do skewness and symmetry affect the choice of statistical measures?
2. What are the differences between mean and median in skewed distributions?
3. How does the IQR provide a better understanding of variation in skewed data?
4. Why is the standard deviation less effective for skewed distributions?
5. What steps can be taken to minimize skewness in data analysis?

**Tip:** Always visualize your data before choosing measures of center and spread to understand its shape and distribution!

The distribution of the amount of salt needed for the egg to float is displayed in a line plot, and students are asked to describe the skewness of the data and select appropriate measures of center and variation.

Analyze the distribution of the amount of salt needed to float an egg in a science experiment. The data shows a left-skewed distribution, making the median and interquartile range (IQR) more suitable than the mean and standard deviation. This example is great for middle school students learning about data interpretation and skewness.
