22
Q

What is the boundary between the fluid and air called in a graduated cylinder?

A

Meniscus

23
Q

Should you read the measurement to the highest or lowest part of the meniscus?

A

Always read to the lowest

24
Q

What is temperature?

A

Temperature is the degree of hot or cold an object is. It is also the average kinetic energy of molecules.

25

What instruments are used to measure temperature?

A

Thermometers

26
Q

A

(C) (9/5) + 32

27
Q

What is the formula for Celsius?

A

(F - 32) (5/9)

28
Q

What is the formula for Kelvin?

A

C + 273

29
Q

Above zero degrees, the actual number of degrees Celsius is higher or lower than Fahrenheit degrees?

A

It’s lower

30
Q

What is Standard Deviation?

A

Standard Deviation is a measure that is used to quantify the amount of variation in a set of data.

31
Q

If the standard deviation is close to 0 what does that mean?

A

It means that the data tends to be very close to the mean.

32
Q

What is variance?

A

Variance is how far away the data point is from the mean?

33
Q

How do you calculate variance?

A

You take the difference between the data point and the mean, square it, and then average the result.

34
Q

What term describes allowing the viewer to make predictions within recorded data?

A

Interpolotion

35
Q

What is it called when you allow the viewer to make predictions about data not yet recorded?

A

Extrapolotion

36
Q

What are the five main types of graphs?

A

Direct, Indirect, Constant, Best Fit Curved, and Best Fit Peak.

37
Q

What axis does the independent variable go on?

A

X-axis

38
Q

What axis does the dependent variable go on?

A

Y-axis

39
Q

True or false? Length is measured in liters

A

False

40
Q

True or false? Nano units are bigger than mili units

A

False

41
Q

If I were to measure how long a road was would I use meters or kilometers?

A

Kilometers

42
Q

If you were finding standard deviation what would you do first?

A

Find the mean of the data points

43
Q

How do you find mode?

A

The number that appears the most

44
Q

How do you find median?

A

Line the numbers up from least to greatest and find the middle value

45
Q

How do you find the range?

A

You take the largest value minus the smallest value

46
Q

How do you find the average?

A

You add all the values together then divide the total by the amount of values you have.

47
Q

How many digits do you need when using a 10cm ruler?

A

Just the one’s place

48
Q

How many digits do you need when your using a 1cm ruler?

A

One decimal place

49
Q

How many digits do you need when using a 0.1cm ruler?
