Criminal Recidivism in Iowa: 2010-2014
Recidivism is defined as the "tendency of a convicted criminal to reoffend". This dataset tracks former criminals from Iowa over a 3 year period after their release from prison to see whether or not they were convicted of a new crime during that time. The recidivism reporting year is the fiscal year (year ending June 30) marking the end of the three year tracking period. Included are the following variables: Fiscal Year Released (the year the individual was released from Prison), the Race, Ethnicity, Sex, and Age of individual when released. Also included are details about the original crime committed along with whether that individual committed a new crime (Recidivism - Return to Prison) within the 3 year window. | statcrunch_featured | Mar 21, 2018 | 3MB | 3644 |

cell_phones.xls
Q1. Based on a recent study, roughly 80% of college students in the U.S. own a cell phone. Do the data provide evidence that the proportion of students who own cell phones in this university is lower than the national figure?
Answer. Most likely not. Ownership of cellphones and ratios do not depend on anything.
Relevant Variables - The cell is the relevant variable and it is categorical.
Analyze Data - The formal analysis of Q1 will pinpoint on searching the population proportion. The correct statistical test is the one sample z-test for the proportion.
Null Hypothesis - Ho: p = 8
Alternative Hypothesis - Ha: p < .8
Outcomes: Cell
Success: yes
Test stat z = -.71, p-value is .239 > .05, so Ho cannot be rejected.
Roughly 78% of the students sampled own a cellphone. Even though 78% percent is less than 80%, there is not enough support to conclude that the exact data holds right for the whole college or that it would be different from the national proportion. | faithnwanne | May 3, 2019 | 8KB | 380 |
Fatal Encounters Updated September 2018
This data set was downloaded from Fatal Encounters, a non-profit organization that is collecting data on Police Involved Deaths. This data set has been truncated to include the subject's name, age at time of death, subject's gender, subjects race, location of death, cause of death and year of death. This does not only include people shot by police, but there are also instances of police that died during fatal encounters. It is good to remind students using this data set that this is a volunteer agency collecting the data from people that are scouring news articles for evidence of these fatal encounters, thus it is not a complete population of fatal encounters, only a very, very large sample. | habarker | Apr 8, 2019 | 3MB | 162 |

3.33 = B+,
3.00 = B,
2.67 = B-,
2.33 = C+,
2.00 = C,
1.67 = C-).
