Name the value that tells how much an object's position changes. It is a vector quantity of the difference between final and initial position. displacement
Name the value that tells how fast an object's position changes. It is a vector quantity of displacement per time. velocity
Name the value that tells how fast an object's position changes. It is a scalar quantity of position change over time. In other words, give the scalar value of velocity. speed
A sprinter runs 300 meters north, then 400 meters east in 100 seconds. Find her average speed. 7 m/s
A sprinter runs 300 meters north, then 400 meters east in 100 seconds. Find her average velocity. 5 m/s

The total length of all pathways of the human circulatory system in on the order of 10^8 m. A typical red blood cell completes a circuit of 3 meters in 1 minute. Find the RBC displacement. 0 m
The total length of all pathways of the human circulatory system in on the order of 10^8 m. A typical red blood cell completes a circuit of 3 meters in 1 minute. Find the RBC speed. 0.05 m/s
The total length of all pathways of the human circulatory system in on the order of 10^8 m. A typical red blood cell completes a circuit of 3 meters in 1 minute. Find the RBC average velocity. 0 m/s
Name the value that tells how fast an object's velocity changes. It is a vector quantity found as the change in velocity over time. acceleration
true or false: (3.2) an object can be accelerating even if its speed is constant. false
What type of motion occurs when acceleration is constant? uniform motion
what is found by adding data sets and dividing by amount of data sets present? (do not say average) mean
what is the exact middle number in a given data set? median
how do you calculate the median of an odd number of data sets? order numbers from least to greatest, find middle number
how do you calculate the median of an even number of data sets? order numbers from least to greatest, find two middle numbers, average
what is the most frequently occurring number in a data set? mode
What is the difference between the smallest and largest numbers in a sample? range
What is the measurement of how much each number in a data set differentiates form the mean? standard deviation

In normal distributions, approximately 99.6% of data is within how many standard deviations of the mean? 3
In normal distributions, approximately 0.4% of data is within how many standard deviations of the mean? greater than 3
In normal distributions, approximately 34% of the data is how many standard deviations above the mean? Approximately 34% of the data is how many standard deviations below the mean? 1
In a normal distribution, data in the Xth percentile is (higher/lower) than X percent of data. higher
In a normal distribution, how many standard deviations below the mean corresponds to the 0.1 percentile? 3
In a normal distribution, how many standard deviations below the mean corresponds to the 2nd percentile? 2
In a normal distribution, how many standard deviations below the mean correspond to the 16th percentile? 1
In the 50th percentile of a normal distribution, what does the data correspond to? mean
In a normal distribution, a data point 1 standard deviation above the mean corresponds to what percentile? 84th
In a normal distribution, 2 standard deviations above the mean corresponds to what percentile? 98th
In a normal distribution, a data point 3 standard deviations above the mean corresponds to what percentile? 99.9th

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
