difference between grouped and ungrouped data

It is obtained by adding the raw scores and dividing the sum by the number of items. Suppose the raw scores are x 1 , x 2 , x 3 ,, x N then, mean where M = mean x = each score or item N = number of items = sigma, which means 'summation of ' Find the mean of 6, 10, 4, 12, 8. M = 8 ..

Naming Compounds With More Than One Different Functional Groups - When the molecule contains two or more dissimilar functional groups, the parent chain is so chosen so as to contain maximum possible number of functional groups. The numbering of the parent cha..

When the molecule contains two or more dissimilar functional groups, the parent chain is so chosen so as to contain maximum possible number of functional groups. The numbering of the parent chain is done so that the functional group of higher priority gets the lower nu..

The members of a certain group possess similar properties but the reactivity may differ, e.g., in case of group I A the reactivity increases as we move down the group from lithium to cesium but in case of VII A it decreases from fluorine to iodin..

Similar physical and chemical properties are shown by elements in a group. However the first member of each group differs from its succeeding members (called congeners). This mainly occurs because of, The small size of the atom and its ion. The high ionization en..

Irrespective of any system of classification that is being used, angiosperms are divided into two natural groups called monocotyledons (or monocots) and dicotyledons (or dicots). This distinction is based on the number of embryonic leaves (or cotyledons) in the embryo. The following table..
