Square root curve calculator helps you to adjust raw scores or grades using the square root function to create a more equitable distribution of grades.

The square root curve is a method of adjusting grades by applying the square root function to the raw scores. This technique is often used to curve grades upward, resulting in a more forgiving distribution of scores.

## Square Root Curve Grade Formula:

Here is the basic formula:

\begin{align*} SRG &= \sqrt{G} \cdot 10 \end{align*}

Where,

**SRG**– The square root curved grade**G**– The student’s raw grade

## How to Calculate Square Root Curve Grade?

When it comes to making a quick and accurate calculation, the square root curve calculator is the most convenient option. However, if you prefer to perform the calculation manually, follow the provided example.

### Example:

Suppose, if a student receives a score of 72 (G) on a test. What is the student's square root curved grade?

### Solution:

Using the formula:

\begin{align*} SRG &= \sqrt{G} \cdot 10 \end{align*}

**Step 1:** Calculate the square root.

√(72) = 8.4852

**Step 2:** Multiply it by 10.

8.4852 × 10 = 84.852

**Step 3:** Round the curved grade to the nearest whole number.

84.852 ≈ 85

Therefore, the student's square root curved grade is 85%.

## Square Root Curve Chart:

Have a look at this chart which displays the visual representation of how the square root function transforms raw scores into curved grades:

Raw Score | Square Root | Curved Score |
---|---|---|

0 | 0 | 0 |

1 | 1 | 10 |

4 | 2 | 20 |

9 | 3 | 30 |

16 | 4 | 40 |

25 | 5 | 50 |

36 | 6 | 60 |

49 | 7 | 70 |

64 | 8 | 80 |

81 | 9 | 90 |

100 | 10 | 100 |

## FAQs:

### How do I Calculate a Test As 20% of a Grade?

Calculating a test as 20% of a grade involves the following steps, such as:

**Identify Weight:**Determine the test's weight in the overall grade (20% in this case)**Calculate Weighted Value:**Multiply your test score by 0.20 (representing 20% in decimal form) to find its weighted value**Add to Overall Grade:**Combine the weighted test score with other graded components to compute your final grade

You can also consider the grade curve calculator for instant results.

### When Should a Square Root Curve Be Used?

A square root curve should be used when there is a clear need to adjust grades upward in order to provide a more forgiving assessment for students. This could be helpful for students who are struggling in a particular subject or have faced unexpected challenges.

However, the square root curve should only be used as a standard practice for some assessments, as it can hide true student abilities.
