Question

# This scatter plot shows the age in years versus the height in inches of a group of children. Explain why the drawn line of best fit is accurate or why not.

Hint:

### Trend lines are used to approximate the pattern or behavior of a set of data. It can be drawn in several ways.

We are asked to check whether the given line is a best fit or not for the given data.

## The correct answer is:

### Step 1 of 2:

It is to be kept in mind that trend lines are used to analyze the behavior and direction of a data set. So, it has to close enough even though not accurate.

We could possibly draw different trend lines for the given scatter plot. But, the line should justify the scatter plot. Make sure, we draw a trend line around which the points align closely and tightly.

Here, there are several points that are far away from the line, So, it’s not the best fit for the given graph.

Step 2 of 2:

The trend line that best fits for the scatter plot is:

The points are closely packed around the line and some even lie on it.

The points are closely packed around the line and some even lie on it.

There could possibly be numerous of trend lines for a given scatter plot. But the one that best fits a graph is the one where the points align around the line and are closely packed.
