Unitary Method

The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.

Speed, Time, and Distance

Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.

Profit and Loss

The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.

Units and Measurements

Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.

### Rat Weight and Length Data Analysis

The data below shows the weight and length of 10 rats. You are required to find the correlation coefficient for this relationship and determine the equation for the regression line. Use weight as the independent variable (x) and length as the dependent variable (y).

**HINT:** Utilize Statcrunch for calculations.

#### Data Table

| Weight (ounces) | Length (inches) |
|------------------|------------------|
| 1.5 | 2.2 |
| 2.3 | 3.9 |
| 2.4 | 4.2 |
| 2.7 | 5.1 |
| 3.4 | 5.1 |
| 3.8 | 5.6 |
| 4.1 | 6.5 |
| 4.3 | 6.2 |
| 5 | 6.8 |
| 5.6 | 7.4 |

#### Required Calculations

**Correlation coefficient:**
_________________

**Regression line equation:**
_________________

**Explanation for Students:**
1. **Correlation Coefficient:** This value explains the strength and direction of the linear relationship between rat weight and length. A value close to +1 indicates a strong positive relationship, while a value close to -1 indicates a strong negative relationship. A value around 0 suggests no linear correlation.

2. **Regression Line Equation:** This line provides a mathematical relationship between weight and length. It can be used to predict the length of a rat based on its weight. It typically has the form $ y = mx + c $, where $ m $ is the slope and $ c $ is the y-intercept.

By analyzing the given data through statistical tools like Statcrunch, these values can be derived accurately.
