Bell Work Draw a scatter plot and describe

Bell Work � Draw a scatter plot and describe the correlation for the table below.

Go back to experiment notes � Levels � How of variables: many variables are being manipulated? � If 5 different exercise routines are being manipulated, what is the level?

Analyzing Results in Research

Descriptive Statistics � Applied to descriptive research � Describes the group researched � Provides a state of current thoughts/emotions/behaviors � Finding the mean on a test shows the average for the students that took the test. � Can we apply this to other class’ knowledge?

Inferential Statistics � Uses a sample � Allows generalizations about entire population � Therefore, it needs an accurate sample. � Participants receiving a new type of drug indicate how the entire population may interact with the new drug.

Note Hand Out

Measures of Central Tendency � Mean: The average of all the data. � Add all the numbers, then divide by the number of participants � Median: The middle. � Half the data is more than, and half the data is less than this number. (Line it up and cross them off) � Mode: The most frequent. � Which number is seen most often. � There can be no mode � Can be more than one mode.

Measures of variance � Range � Difference � Standard between the highest and lowest scores Deviation � Calculated to find the average distance from the mean.

Together: Find the mean, median, and mode
