  • How do you calculate statistics?

    How to calculate a test statistic

    1. Find the raw scores of the populations.
      2. Assume you want to perform a z-test to determine whether the means of two populations are equal.
    2. Calculate the standard deviation of the population
    3. Calculate the population mean
    4. Evaluate the z-value
    5. Apply the t-test formula
    6. Interpret the results

  • How to do statistics calculations?

    To start a statistical calculation, perform the key operation (STAT) to enter the STAT Mode and then use the screen that appears to select the type of calculation you want to perform.
    Pressing any of the above keys ( to ) displays the Statistics Editor..

  • How to perform statistical analysis?

    In most studies, a p-value of 0.05 or less is considered statistically significant — but you can set the threshold higher.
    A higher p-value of over 0.05 means variation is less likely, while a lower value below 0.05 suggests differences.
    You can calculate the difference using this formula: (1 - p-value)*100..

  • What is the description of a calculator?

    A calculator is a machine which allows people to do math operations more easily.
    For example, most calculators will add, subtract, multiply, and divide.
    Some also do square roots, and more complex calculators can help with calculus and draw function graphs..

How to Calculate Standard Deviation

Standard deviation is a measure of dispersion of data values about the mean.
The formula for standard deviation is the square root of the sum of squared differences from the mean divided by the size of the data set.

,

How to Calculate The Mean

The mean is the sum of all of the data values divided by the size of the data set.
The mean is also known as the average.
To find the mean add all of the values and divide by the count.
The only difference between a sample mean and a population mean is the symbol used to express the mean.

How to Find The Maximum

Ordering a data set from lowest to highest value, x1 ≤ x2 ≤ x3 ≤ . ≤ xn, the maximum is the largest value in the data set, xn.
The formula for maximum is:

,

How to Find The Median

Ordering a data set from lowest to highest value, x1 ≤ x2 ≤ x3 ≤ . ≤ xn, the median is the value separating the upper half of the ordered data from the lower half.
If n is odd the median is the center value.
If n is even the median is the average of the 2 center values.
If n is odd the median is the value at position p where If n is even the medi.

,

How to Find The Minimum

Ordering a data set from lowest to highest value, x1 ≤ x2 ≤ x3 ≤ . ≤ xn, the minimum is the smallest value in the data set, x1.
The formula for minimum is:

,

How to Find The Mode

The mode is the value or values that occur most frequently in the data set.
Count the number of times each value in a data set occurs.
The mode is the data value with the highest count.

,

How to Find The Range

The range of a data set is the difference between the minimum and maximum.
To find the range, calculate xn minus x1.

,

How to Find The Sum

The sum is the total of all data values added together, x1 + x2 + x3 + . + xn.
The formula for sum is:

,
