For warrant in to ruminate the learning ability of an individual he would be tried and true at the mount up of 20 , then tested again 10 sexagenarian age later at 30 , and then again by and by a further 10 years in the nett test at 40 years . Thus a participant would be tested three times everywhere two years cross-section(a) regularity , on the other march on , studies people at varying phases of development at wizard point in time it seeks to compare groups of people of heterogeneous sequences on like tasks at one time , inherently confound bestride and generational membership . For example , a cross-sectional stud y might involve administering cognitive tests to a different age groups , let s say , 10- , 20- , 30- , 40- years old , and then compare the means of the groups . This approach can herald the average age at which certain skills or abilities come in . However , the entropy collected in cross-sectional studies tells secondary around the unquestionable development of any single individual . Moreover , the cross-sectional method solely provides information about age differences , not age related change . The biographic method , in contrast to cross-sectional method , is an attack to reconstruct the deportment course by interviewing the person and by using various other sources , much as the biographer does in writing a book-length intent story .
