When a researcher undertakes a project to do research firstly he takes some random samples. Sample is definite a small group of numbers assume to represent the whole population. Suppose a researcher wants to do research on married couples to find the trend of divorce among them. For that reason he will randomly choose some of the couples and will draw conclusions that inter personal communication reduce the chances of divorce.

Explanation:
Our neighbor, Lamont has fruit trees on his property. "Lamont, what kinds of fruit do you grow?" I asked. "Well I grow peaches, apricots, pears and plums" he replied. "Wow! That's quite a variety" I said. Lamont's son Riley helps his dad care for the trees. "Oh it's constant work and care" Riley said, "but the delicious results are worth the effort". After the fruit is harvested Riley's mother Charlotte cans the fruit for use throughout the year. She makes preserves and she gives them as gifts for special occasions. Charlotte sells some of her preserves to Kurt Simmons the owner of a local shop. People come from all over the county to buy Charlotte's preserves. Riley's Aunt Fay grows corn, tomatoes, beans and squash in her garden. Each year she selects her best vegetables and enters them in the fair. She has won blue ribbons medals and certificates for her vegetables. "Oh I just like being outside. That's why I enjoy gardening" Fay said. Fay's specialty squash-and-tomato bread is one of the most delicious breads I have ever tasted.
