Topic 5 – Statistical Models Class 2 – Measures of Center and Spread Mr. Solórzano – Algebra 1

Objectives Students will use measures of center to represent a whole data set Students will find measures of spread to describe the consistency of the data

Quiz Complete a second table showing the relative frequency of the data rounded to the nearest thousandth What is the probability that a randomly selected student is a boy, given that they are studying French? What is the probability that a randomly selected student is studying Spanish, given that the student is a girl? What is the probability that a randomly selected student is both a boy and is studying Chinese?
