Asample is drawn from a well-shuffled deck of cards that contains 13 hearts, 13 clubs, 13 spades, and 13 diamonds. what is the best example of a non-representative sample? a. a sample of 10 cards that includes 3 hearts, 3 clubs, 2 spades, and 2 diamonds. b. a sample of 10 cards that includes 10 hearts. c. a sample of 10 cards that include 3 hearts, 2 clubs, 2 spades, and 3 diamonds. d. a sample of 10 cards that includes 2 hearts, 2 clubs, 2 spades, and 4 diamonds.

Answer : B. A sample of 10 cards that includes 10 hearts.

A representative sample is a small quantity that is similar to the large quantity.

It means small quantity should reflect the larger quantity.

For example in a classroom of 25 students having 10 girls and 15 boys.

The representative sample includes 4 students : 2 boys and 2 girls

Given :

A sample is drawn from a well-shuffled deck of cards that contains 13 hearts, 13 clubs, 13 spades, and 13 diamonds.

Options A, C and D reflects the given sample 13 hearts, 13 clubs, 13 spades, and 13 diamonds.

Option B includes only 10 hearts. clubs, spades and diamonds are not included. So this is the best example for non - representative sample.

"it's not the heat, it's the humidity".   that's a partly valid phrase you may have heard in the summer, but it's actually both.   the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature.   this has important considerations for the human body's comfort.   when the body gets too hot, it begins to perspire or sweat to cool itself off.   if the perspiration is not able to evaporate, the body cannot regulate its temperature.   evaporation is a cooling process.   when perspiration is evaporated off the body, it effectively reduces the body's temperature.   when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases.   in other words, the human body feels warmer in humid conditions.   the opposite is true when the relative humidity decreases because the rate of perspiration increases.   the body actually feels cooler in arid conditions.   there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).
