    Mean and Standard Deviation of Discrete Random Variables

     

    11/12

    Today we discussed transforming data and recalculating mean and standard deviations

    Transformations are when we create a new function by multiplying and adding or subtracting. 

    Notes

     

    11/13

    Today we discussed creating new functions by combining functions and seeing the effects of the mean and standard deviation

    Today we learned how to use the z-table and calculators to find z-scores associated withh areas under the normal curve.

    In other words, we usually have a value, obtain a z score, and determine the area udnerneath.... But today we were given the area underneath, determined the z-score associated, and found the vlaue associated with that z score.

    Today we talked about percentiles and z-scores

    Notes

    At the end of the day, Percentiles and Z-Scores show the position of data relative to the rest of the data. This is wildly important!

    Today was a work day to digest all the ideas about percentiles, z-scores, and data analysis. 

    There were a LOT of khan academies but you had 50 minutes to work on them 

    Get them done, this is a great foundation for Q2 to build on :) 

     

    10/18-10/19

     Today we learned about the normal distribution, the empiracal rule, and using the z-tables to find areas under the normal distribution

    Normal and Z-Table

    3 Khans on the normal distribution
