# How do you calculate geometric mean in SPSS?

## How do you calculate geometric mean in SPSS?

Harmonic and geometric means are both available in the MEANS command in SPSS. In the SPSS menus, select Analyze>Compare Means>Means, then click on the Options button and select them from the list of available statistics on the left.

**How do I find my GM?**

Basically, we multiply the numbers altogether and take the nth root of the multiplied numbers, where n is the total number of data values. For example: for a given set of two numbers such as 3 and 1, the geometric mean is equal to √(3×1) = √3 = 1.732.

**How do you find the geometric mean of ungrouped data?**

Geometric Mean (G.M): The nth root of the product of the values is called Geometric Mean.

- Geometric Mean for Ungrouped Data: If x₁, x₂, …, xn be n observations, then geometric mean is given by G = (x. x.…. xn)1n,
- G. M=(3.32….. 3n)1n,
- Solution: G. M=(2.22….. 2n)1n (∵ First n terms 1, 2, 3, …, n = n (n + 1)/ 2)

### How is the arithmetic mean calculated using SPSS?

Calculate Mean & Standard Deviation in SPSS

- Click Analyze -> Descriptive Statistics -> Descriptives.
- Drag the variable of interest from the left into the Variables box on the right.
- Click Options, and select Mean and Standard Deviation.
- Press Continue, and then press OK.
- Result will appear in the SPSS output viewer.

**What is a harmonic mean SPSS?**

The harmonic mean is the total number of samples divided by the sum of the reciprocals of the sample sizes. Kurtosis . A measure of the extent to which there are outliers.

**What is the full form of GM in measurement?**

gm (gram): The abbreviation gm stands for gram, a unit of measurement of weight and mass in the metric system. In weight, a gram is equal to a thousandth of a kilogram. In mass, a gram is equal to a thousandth of a liter (one cubic centimeter) of water at 4 degrees centigrade.

#### What is GM in weight?

gram (g or gm) The gram (abbreviation, g or gm) is the cgs (centimeter/gram/second) unit of mass. A force of one dyne (1 dyn), applied to a mass of one gram (1 g), will cause that mass to accelerate at one centimeter per second squared (1 cm/s2).

**How do you find the geometric mean percentage?**

The geometric mean is: [(1.03*1.05*1.08*. 99*1.10) ^ (1/5 or . 2)]-1= 4.93%. The average return per year is 4.93%, slightly less than the 5% computed using the arithmetic mean.

**What’s the difference between arithmetic mean and geometric mean?**

Arithmetic mean is defined as the average of a series of numbers whose sum is divided by the total count of the numbers in the series. Geometric mean is defined as the compounding effect of the numbers in the series in which the numbers are multiplied by taking nth root of the multiplication.

## Why geometric mean is used?

In statistics, the geometric mean is calculated by raising the product of a series of numbers to the inverse of the total length of the series. The geometric mean is most useful when numbers in the series are not independent of each other or if numbers tend to make large fluctuations.

**What is geometric mean and harmonic mean in statistics?**

Geometric and Harmonic Mean The geometric mean (G.M.) and the harmonic mean (H.M.) forms an important measure of the central tendency of data. They tell us about the central value of the data about which all the set of values of data lies.

**How do you calculate the geometric mean in SPSS?**

Load up SPSS. Click “Transform” from the menu bar at the top of the screen, then click “Compute.” In the “Target Variable” box, type a name for the new variable. This will be the log of the variable that you want the geometric mean of, so “log_yourvariable” would be a suitable descriptive name.

### How do you find the geometric mean on a calculator?

In your “Output” window, scroll down until you find your variable, then locate the “Mean” column. In the calculator window, type “10” and then press the “x^y” — sometimes labeled “y^x” — button. Type in the mean from the table. Press the “Equals” button. The result is the geometric mean.

**What is the geometric mean in statistics?**

The geometric mean is an average that multiplies all values and finds a root of the number. For a dataset with n numbers, you find the n th root of their product. You can use this descriptive statistic to summarize your data.

**What is the cells subcommand in SPSS?**

SPSS MEANS – CELLS Subcommand. The syntax below has a second line containing a CELLS subcommand. It specifies which statistics (columns) are included in which order. Note that MEANS has more options here than DESCRIPTIVES, all of which can be included by specifying ALL on the CELLS subcommand.
