How to Find Standard Deviation on TI 36X Pro? How to Calculate?

Texas Instruments TI 36X Pro scientific calculator is one of the most popular and powerful calculators around which allows you to calculate summary statistics as mean and standard deviation.

Though a user guide comes with the TI 36X Pro calculator on how to use the calculator including the method to calculate standard deviation, many users can’t find how to do it.

If you are one of them who is having problems finding standard deviation on your TI 36X Pro calculator then don’t worry, we are here to help you. The complete direction to calculate deviation is described in this article in a simplified way.

Let’s check it out.

How To Find Standard Deviation On TI 36X Pro Calculator?

As you know the method to calculate standard deviation, now let’s see how you can find that using your TI 36X Pro scientific calculator.

You can do it simply in 2 steps:

1. Enter data
2. Calculate the value

The calculation process for one-variable statistics and two-variable statistics is different. So, both processes are given below.

1. For One-Variable Statistics

Finding a standard deviation value for one variable is quite easy. Here are the steps that you will need to follow.

Step 1: Clear All Data

After turning on the Calculator, press the [data] button. Now, there you will be able to input the data. But if there are any data available, you will need to delete them first.

• press the [data] button again
• Then, there you will get a few options for a clearing list. Select the option that you need.
• Finally, press [enter] to clear the data

Step 2: Enter Data

• At first, press the [data] button
• Then, press the [enter] button
• After that, enter values and frequencies into the “lists”
• Finally, press the [2nd] button and then the [mode] button

Step 3: Calculate Mean, Standard Deviation, Five Number Summary

• First, press the [2nd] button, and then the [data] (stat-reg/distr) button
• Then, select “2: 1-Var Stats” and press [enter]
• After that, select the “list” in which you’ve entered the data value
• Now, input the value for “FRQ”
• If the frequency is not given then select “ONE” for “FRQ”
• If the frequency is entered in a list, select the “List” for “FRQ”
• Finally, select “CALC” to obtain the variable information
• The mean value is “X” and the standard deviation value is “Sx”.

2. For Two-Variable Statistics

For two-variable statistics, the process is little  bit different from one-variable statistics. Here are the necessary steps that you will need to follow.

Step 1: Clear All Data

After turning on the Calculator, press the [data] button. Now, there you will be able to input the data. But if there are any data available, you will need to delete them first.

• press the [data] button again
• Then, there you will get a few options for a clearing list. Select the option that you need.
• Finally, press [enter] to clear the data.

Step 2: Enter Data

• At first, press the [data] button
• Then, press the [enter] button
• After that, enter values and frequencies into the “lists”
• Finally, press [2nd] and then[mode]

Step 3: Calculate Linear Regression

• At first, press the [2nd] button and the [mode] button
• Then, select “2: 1-Var Stats” and press the [enter] key
• Now, select the “lists” that contain the “X” and the “Y” data value
• After that, input the value for “FRQ”
• If the frequency is not given then select “ONE” for “FRQ”
• If the frequency is entered in a list, select the “list” for “FRQ”
• Finally, select the “CALC” option to obtain the variable information
• The slope (b₁) is “a” and the intercept (b₀) is “b”.

Frequently Asked Questions

How Do I Define Statistical Data Points On A TI-66X Pro Calculator?

To do so, Press data > Input data points > enter > 2^nd > data > select 2: 1-Var Stats > select [L1] for DATA and ONE for FRQ > CALC > enter.

How Do You Find The Standard Deviation On A TI 30X?

The process is very easy. Press data > provide data into the lists > 2^nd > data > Stat > 1-VAR > choose the list from the data option > CALC > enter > 2^nd > MODE > STAT.

How Do I Calculate Standard Deviation?

Calculating standard deviation is very easy. First, you will need to find the mean and then square the distance to the mean for each data point. Now, sum the values and divided the sum by the number of data points. Lastly, square root the quotient.

How Do I Do Normalcdf On A TI-36X Pro?

To do Normalcdf, press 2^nd > data > select DISTR using the right arrow > choose 2: Normalcdf > enter > input the required values > enter.

Conclusion

TI 36X Pro scientific calculator is perfect for calculating mid and big-ranged equations. So, the calculation of standard deviation on this powerful calculator is quite easy and simple. You just need to clear previous data, input new data, and calculate the value of standard deviation as instructed above in this article.
