a.) POPULATION b.) SAMPLE a.) The ENTIRE GROUP of objects, individuals, or events is called the _____________. b.) A part of the entire group that is chosen to represent the group is called a __________. a.) POPULATION b.) SAMPLE

When a sample does NOT accurately represent a population, it is called a _________ ______________. Biased Sample Category 1 - 10

According to this sample, the majority of people exercise between ___ and ___ hours per week. Category 1 - 20 4 and 6 hours

According to the sample, the middle HALF of the class scored between what two %s on the last test? around 23%-70%

What 5 values do we need to find to create a Box Plot? 1- Least Value 2- Greatest Value 3- Median 4- Lower Quartile 5- Upper Quartile

Boys’ median height is greater. Compare the centers (MEDIANS) of the dot plots. Boys’ median height is greater. Boys: 69 inches Girls: 66.5 inches

Compare the spreads of the dot plots by calculating the RANGES. They both have a range of 8 inches.

Is the variability similar or different in these box plots?

Visually compare the SHAPES of the dot plots. For class 1, the data is clustered to the left. The data is fairly evenly distributed and centered in the middle for Class 2.

When the Mean Absolute Deviation is greater, that means there is _________ variability in the data.

____________ Probability is the probability of how an event SHOULD occur before the actual experiment. Theoretical

   

When finding the theoretical probability of compound events, it helps to create a _________ or __________ ___________. Table; Tree Diagram

SIMPLE COMPOUND A ___________ event only has ONE outcome. A _________ event is an event made up of two or more events. SIMPLE COMPOUND

To find the number of TOTAL possible outcomes of a COMPOUND EVENT, you can _________ the number of choices for each event. MULTIPLY

____________ Probability is according to what actually happened ____________ Probability is according to what actually happened. The event occurred, and you show what happened. Experimental

What is the formula for Experimental Probability?  

A dentist has 400 patients with a range of ages A dentist has 400 patients with a range of ages. What is the experimental probability that the next patient will be FEMALE and in the age range 22-39? Range: 10-21 Range: 22-39 Range: 40-50 Range: 50 + Male 44 66 32 53 Female 36 50 45 74  

The _____________ of an event includes ALL of the outcomes NOT included in the regular event. COMPLEMENT

When making a prediction using experimental probability, use a _________. PROPORTION

Is the following a BIASED SAMPLE or a RANDOM SAMPLE? Paula wants to know the favorite type of music for students in her class. She puts the names of all students in a hat, draws 8 names, and surveys those students. Random Sample

Describe the process of calculating the Mean Absolute Deviation. 1.) Find the mean. 2.) Subtract each data point from the mean and find its absolute value. 3.) Find the mean of the absolute values of these differences.

Is the median or mean impacted more by an outlier in a set of data Is the median or mean impacted more by an outlier in a set of data? EXPLAIN! Mean -The median is not impacted by an outlier because it is found by crossing out values on the outside.

Set up a proportion for this probability problem: The experimental probability that it will rain on any day is about 15%. Out of 365 days, about how many days can residents predict rain?  

What’s the difference between mean and median? Median is the MIDDLE number of the data. The Mean is the AVERAGE of the data.
