24
Q

What type of study involves observation of some subset of a population of items all at the same time, in which groups can be compared at different ages with respect to independent variables

A

Cross-sectional studies

25
Q

Contracted by inhalation or contact with lesions

Common in silica workers, people exposed to heat and organic dusts, medical employees, animal caretakers

A

26
Q

Can be described as the number of scores that are free to vary

A

Degrees of freedom

27
Q

Formula for Impedence

A

I=V/A

Voltage / Amperage

28
Q

Under what conditions is the following equation used to measure Wet Bulb Globe Temperature

0.7WB + 0.2GT + 0.1DB

A

Outdoors w/ a solar load

29
Q

What is Boyles Law?

A

States that when pressure exerted by a gas is reduced, the volume increases

At a constant TEMPERATURE, a fixed mass of gas occupies a volume that is inversely proportional to the pressure exerted on it.

30
Q

A

Indoors or outdoors without a solar load

32
Q

Defined as the rate at which electrical energy is transferred between circuits

A

Power

33
Q

How is minimum sample volume calculated?

A

LOQ multiplied by 1000 divided by contamination target concentration

34
Q

What is the reference value (reference level) used for sound power calculations?

A

10 -12 W

35
Q

How many samples should be collected in a employee group of 8

A

7

36
Q

What is Charles’ law?

A

At a constant PRESSURE, the volume occupied by a fixed mass of gas is directly proportional to the absolute temperature.

37
Q

What type of study is used to determine the degree of associations between various risk factors and outcomes

A

Case-control study

38
Q

Reflection of correlation between two sets of numbers

Q

Middle value in a list of data?

A

Median

For example if a list has nine numbers, the middle number would the median

47
Q

Defined as the probability of obtaining a result as extreme as the one observed, assuming that the null hypothesis is true

A

P-value

  • the lower the p-value, the less likely the result
48
Q

An equation used to calculate the correlation between variables

A

Correlation coefficient

49
