Question 1

Multiple scorers timing a 100-m dash should give the same runner the same score. The relationship between these scores is a measure of _____________.
A) speed
B) reliability
C) validity
D) agreement

Accepted Answer

Reliability refers to the consistency of a measure, in this case, the consistency across multiple scorers in timing a 100-m dash for the same runner.

Question 2

In a group of performance scores for athletes, the ________ is the arithmetic average.
A) mean
B) mode
C) median
D) standard score

Accepted Answer

The mean is the arithmetic average of a group of numbers, and thus would be the appropriate measure of central tendency to use for performance scores. The mode is the most frequent score, but may not necessarily be representative of the entire group, and the median is the middle value of a group of numbers and may also not be the most appropriate measure for performance scores. The standard score is a measure of how many standard deviations a score is above or below the mean, and would not be the appropriate measure for finding the average score.

Question 3

The most often used test for core body endurance is the:
A) push-up
B) 40-yd dash
C) chin-up
D) sit-up

Accepted Answer

The sit-up test is most commonly used to assess core body endurance, as it specifically targets the abdominal muscles, which are central to core strength and stability.

Question 4

In a group of test scores, the ______________ is the middle score from the entire group of scores.
A) arithmetic score
B) mode
C) median
D) t-score

Accepted Answer

The median is the middle score in a group of test scores, dividing the scores into two equal halves. It is not affected by extreme scores (unlike the mean) and is a better representation of the central tendency of the dataset.

Question 5

A female basketball player has the following test results: 1-RM bench press, 150 lb; sit-ups, 60; push-ups, 45; vertical jump, 12 in.; 20-yd dash, 2.8 s.; mile run, 5 min 22 s. The area she needs to focus on the MOST is:
A) lower-body strength and power
B) upper-body strength and power
C) upper-body endurance
D) core-body strength and endurance

Accepted Answer

Although the athlete has strong upper-body strength, as evidenced by her 1-RM bench press and push-up results, her vertical jump and 20-yd dash times suggest that her lower-body strength and power could use improvement. Focusing on exercises such as squats, lunges, and plyometric drills can help improve this area.

Question 6

In testing athletes, proper amounts of rest are needed to ensure that the test really measures what it is supposed to measure. Maximal anaerobic tests that cause high levels of lactic acid to build up in the body may require up to _____________ before further testing occurs.
A) 5 minutes
B) 15 minutes
C) 30 minutes
D) an hour or more depending on conditions and fitness levels

Accepted Answer

Maximal anaerobic tests that result in high levels of lactic acid in the body may require an hour or more of rest before further testing occurs. The exact amount of rest needed can vary based on individual fitness levels and testing conditions. It is important to ensure that athletes have had enough rest before conducting further testing to ensure accurate results. Rest allows the body's metabolic processes to return to baseline levels and helps prevent fatigue from affecting subsequent tests.

Question 7

In the testing of athletes who will be compared to each other, motivation should
A) be high
B) be low
C) be consistent
D) not be given

Accepted Answer

In testing athletes who will be compared to each other, it's crucial that their motivation levels are consistent to ensure that the comparison is fair and that differences in performance are due to actual differences in ability, skill, or condition, rather than varying levels of effort or motivation.

Question 8

A 6-ft, 3-in., 245-lb high school football defensive lineman has the following physical test scores: bench press, 250 lb; squat, 130 lb; 40-yd dash, 5.4 s; seated 4-lb medicine ball push, 21 ft, mile run, 6 min 33 s. The area he needs the MOST work in is:
A) lower body strength and power
B) lower body endurance
C) upper body strength and power
D) cardiorespiratory endurance

Accepted Answer

The athlete's squat of 130 lb is significantly lower than what would be expected for someone of his size and bench press capability, indicating a need for improvement in lower body strength and power.

Question 9

What is the range of Z scores?
A) +1 to -1
B) +2 to -2
C) +3 to -3
D) +4 to -4

Accepted Answer

The range of Z scores is always from -3 to +3. This is because a Z score represents the number of standard deviations away from the mean, and any score more than 3 standard deviations away from the mean is considered extremely unlikely. Thus, the correct range of Z scores is +3 to -3.

Question 10

Test scores that possess an absolute zero, contain no negative numbers, and represent absolute differences between scores are termed ___________ scores.
A) ratio
B) interval
C) ordinal
D) nominal

Accepted Answer

Ratio scores possess an absolute zero, where a score of 0 means the absence of the variable being measured. This type of score also represents absolute differences between scores and does not contain negative values. Examples of ratio scores include weight, height, and number of correct answers on a test with no partial credit.

Question 11

A group of individuals who share a common characteristic is termed a ______________.
A) population
B) subpopulation
C) sample
D) subsample

Accepted Answer

A population refers to the entire group of individuals who share a common characteristic or set of characteristics.

Question 12

If the plotted scores from a test represent a bell-shaped curve, then approximately ______ of the scores fall within plus or minus one standard deviation of the mean.
A) 34%
B) 50%
C) 68%
D) 95%

Accepted Answer

The bell-shaped curve is a normal distribution, and approximately 68% of the scores fall within plus or minus one standard deviation of the mean in a normal distribution.

Question 13

The standard deviation of a set of scores describes the ________________ of that data set.

Accepted Answer

The answer of The standard deviation of a set of...

Question 14

The mean is a measurement that represents _____________ ______________.

Accepted Answer

A sample, or small number of individuals, drawn from a larger population of individuals that share a common characteristic is termed a _____________.

Accepted Answer

The answer of A sample, or small number of individuals,...

Question 17

A standardized score where the mean is set to 50 with scores over 50 representing individuals scoring above the mean and scores below 50 representing individuals scoring below the mean is called a _____________.

Accepted Answer

The answer of A standardized score where the mean is...

Question 18

The results of a testing program should be used to direct athletes to a sport suited to their physiques.

Accepted Answer

The results of a testing program should not solely determine the sport an athlete pursues, as factors such as interest, passion, and mental attributes also play significant roles in athletic success and satisfaction.

Question 19

During testing athletes should wear shoes designed for the surface.

Accepted Answer

Wearing shoes designed for the surface during testing ensures safety and optimal performance.

Question 20

A quantitative score derived from testing is termed a measurement.

Accepted Answer

This is true, a measurement is a quantitative score that is derived from testing.
