$There\:are\:three\:advantages\:in\:using\:a\:cluster\:sample\:$
$instead\:of\:other\:types\:of\:samples\:are\\$
$\left(1\right)\:A\:cluster\:sample\:can\:reduce\:the\:cost.\\\left(2\right)\:It\:can\:simplify\:fieldwork.\\\left(3\right)\:It\:is\:convenient.\\There\:are\:major\:disadvantage\:of\:cluster\:sampling\:$
$is\:that\:the\:elements\:in\:a\:cluster\:may\:not\:have\:the\:same\:$
$variations\:in\:characteristics\:as\:elements\:selected\:individually\:$
$from\:a\:population.\:The\:reason\:is\:that\:groups\:of\:people\:may\:$
$be\:more\:homogeneous\:in\:specific\:clusters\:such\:as\:$
$neighborhoods\:or\:clubs.$
