Correlation • The Correlation analysis tool measures the relationship between two data sets that are scaled to be independent of the unit of measurement. The population correlation calculation returns the covariance of two data sets divided by the product of their standard deviations based on the following formulas. www.afterschoool.tk

AFTERSCHO☺OL's MATERIAL FOR PGPSE PARTICIPANTS

COVARIANCE •

• • • • • • • • •

Returns covariance, the average of the products of deviations for each data point pair. Use covariance to determine the relationship between two data sets. For example, you can examine whether greater income accompanies greater levels of education. Syntax COVAR(array1,array2) Array1 is the first cell range of integers. Array2 is the second cell range of integers. Remarks The arguments must either be numbers or be names, arrays, or references that contain numbers. If an array or reference argument contains text, logical values, or empty cells, those values are ignored; however, cells with the value zero are included. If array1 and array2 have different numbers of data points, COVAR returns the #N/A error value. If either array1 or array2 is empty, COVAR returns the #DIV/0! error value.

Sampling • The Sampling analysis tool creates a sample from a population by treating the input range as a population. When the population is too large to process or chart, you can use a representative sample. You can also create a sample that contains only values from a particular part of a cycle if you believe that the input data is periodic. www.afterschoool.tk

T Test •

The t-Test analysis tools test the means of different types of populations. • t-Test: Two-Sample Assuming Equal Variances This analysis tool performs a two-sample student's t-test. This t-test form assumes that the means of both data sets are equal; it is referred to as a homoscedastic t-test. You can use t-tests to determine whether two sample means are equal. • t-Test: Two-Sample Assuming Unequal Variances This analysis tool performs a two-sample student's t-test. This t-test form assumes that the variances of both ranges of data are unequal; it is referred to as a heteroscedastic t-test. You can use a t-test to determine whether two sample means are equal. Use this test when the groups under study are distinct. Use a paired test when there is one group before and after a treatment.
