Critical Value Calculator vs Slope Calc - Step by step Usage & Stats
Perform hypothesis testing through our efficient critical value calculator.
Critical value calculator, a hands-on tool for statisticians, calculates t-value and z-value with a click. Single t-value calculator and z-value calculator are available for use yet, they do not suffice the needs of students. However, in this critical score calculator you can calculate both critical values.
Now you can get rid of tiresome practice of looking through hundreds of t- and z-value tables because critical value calculator calculates them in an instant.
How to perform calculations:
Calculate t-value
1. Specify the significance level in the given box.
2. Select degrees of freedom.
3. Calculate t-value
Calculate z-value
1. Enter the significance level in the input box.
2. calculate p-value
You can reset the critical value calculator by pressing “reset” button.
Basic definitions:
1. Critical value: It is the cut-off value of the graph generated by the test static and shows the region where test static does not lie. Critical value depends upon the significance level. T tells whether to accept of discard null-hypothesis.
2. Significance level: Significance level or statistical significance determines that the difference in population cannot be only associated with chance.
3. Null hypothesis: A hypothesis that describes no difference between two data. And if any difference is seen it appears only by chance. It is abbreviated as (Ho).
4. T-value: It is the calculated difference in the graph relative to the data.
5. Z-value: It is a cut-off point area under the standard distribution of data.

Why do we use slope calculator?
Calculating the slope of a line is a bit tricky and lengthy task, we can use the slope calculator to calculate the slope “m” of a linear equation. You can calculate the following terms.
Slope from the equation of a line.
Slope from two points.
What is the slope of a line?
The slope of a line is the steepness of a line or a curve, some other names for the slope are “gradient, slant, and incline.” To calculate the slope, we use the following formula.
General formula of the slope:
Generally, we use the following formula to calculate the slope “m”.
m = rise / run = (y2 – y1) / (x2 – x1)
1. “x1, x2, y1, and y2 are the points on which the line lies on the cartesian coordinate.
2. “m” is the slope.
Topographies:
This slope calculator has many features that make it unique compared to other calculators.
Input field:
The input fields are very easy to use and very flexible. Separate boxes are designed for the ease of the user.
Erasing all input:
The “reset” button allows you to erase all the input at once.
Calculate button:
To calculate the result just tap on the “calculate” button. It will navigate you to the result screen.
Mathematical format:
Throughout the result section, “LaTeX” is used. LaTeX is a mathematical format used for writing mathematical expressions that makes the output easier to understand.
UI/UX:
This application has an amazing UI/UX that provides a user-friendly environment. Anyone can use this slope calculator easily.
How to use the slope calculator?
The procedure to calculate the slope with steps is quite easier with the help of this Slope calculator. You just have to follow the below steps:
1.Select the input type, “Line equation” or “Two points”.
2.Enter the values in the dedicated input boxes.
3.Press the “Calculate” button.
In this way, you will get the step-by-step solution of the input. Install this application and make the calculation easier.
