In August in Florida, the daily high temperatures are typically high with only a few relatively cool days. A frequency distribution graph showing daily average temperatures in Florida for August would probably form a negatively skewed distribution.

If a researcher measures two individuals on an ordinal scale, it is possible to determine how much difference exists between the two people.

The median is the best measure of central tendency to use in order to describe the distribution of scores below pertaining to the average daily coffee consumption of a sample of individuals.   Daily Cups of Coffee Consumed (X)          f 4 or more                                                     2 3                                                                   2 2                                                                   1 1                                                                   3 0                                                                   3

A distribution of scores has a mean of 52, a median of 54, and a mode of 56. Based on this information, it appears that the distribution is symmetrical.

If a set of scores covers a range of 70 points, then the grouped frequency table for the scores should use an interval width of 7 points.

The median is considered to be the “balance point” for a distribution because it is the score for which the total distance between scores below the median and the median is identical to the total distance between scores above the median and the median.

A grouped frequency distribution table lists one interval as 15-20. The width of this interval is 5 points.

Which of the following statements is(are) TRUE regarding personnel monitoring devices?     1. Personnel monitors are considered to be one of the best methods of protecting          radiographers from radiation exposure.     2. Personnel monitors provides an indication of the working habits and working conditions          of imaging personnel.     3. Personnel monitors determine occupational exposure by detecting and measuring the          quantity of ionizing radiation to which the dosimeter has been exposed.

Which of these can measure exposure rates as low as 10 Gya per hour?

The total TEDE for whole body occupational exposure is?
