characteristic or measure obtained using data values from a specific sample. The Measures of Central Tendency are: • The Mean • The Median • The Mode • The Midrange • The Mean The mean is the sum of the values‚ divided by the total number of values. Sample mean: [pic] where n is the sample size Population mean: [pic] where N is the population size • The Median The median of a data set is the value in

drops of Mayana extract which will be obtained by decoction‚ will be placed in a dry test tube. Then‚ three drops of acetic anhydride and a drop of concentrated sulphuric acid. A green or blue-green color reaction means that the extract is positive of triterpenes and sterols. This also means that the extract is ready to use in making the ointment. In making the experimental product‚ the researcher will first use the decoction method to get the needed extract from the Mayana leaves. In decoction‚ the
