 * Brain Storm Ideas For Topic:**
 * Number of adults sentenced vs Type of crime
 * Years Sentenced vs Type of crime
 * Number of adults sentenced vs years sentenced
 * Males sentenced vs females sentenced
 * Years sentenced vs age of people sentenced

2) Do different types of crime give you different amounts of years sentenced 3) What is the most common amount of years sentenced 4) What gender goes to jail the most 5) Does the age of people sentenced affect the number of years sentenced in Ontario, in which I will be looking at sentences between 2003 and 2007.
 * Main Question**
 * 1)Does the number of homicide cases go down during periods of high prison population in Canada, between the years of 2003 to 2007**

For question one I believe the number of people sentenced to jail for homicide is lower in years when jail population is highest. I believe this to be true because the people likely to comitt these crimes are allready in jail. So if current prison population is high new sentencing should be lower. I believe the correlation between the amount of people sentenced to the amount of people in jail will show a negative moderate correlation.
 * Hypotheses**

I chose this topic because I was interested in something to do with crime and jail. I then narrowed the topic to homicide and jail population.

The amount of people founded guilty of homocide was highest in 2004/2005

118, 122, 109, 115 mean= 116 median= 116.5 mode= 116 standard deviation= 200.92 The amount of people that went to prison for homocide is highest in 2004/2005 75 910, 79 172, 82 647, 83 043 mean= 80 193 median=80 909.5 mode= 80 193 The number of people sentenced to prison is highest in 2006/2007


 * Two variable calculations**



Stratified sample is used in these tables. The tables surveyed everyone who has been in court for homicide. These characteristics make it a stratified sample.

The bias in these data tables is they didn't consider homicide cases that havn't been solved yet. This bias is considered a non response bias because homicide cases that havn't been solved yet are not included in the statistics. The data I found also only had a limited range of years provided. I could only find informationg for four years. Four years isn't enought to draw a thorough conclusion. Finally there is a measurement bias because I am counting the number people sentenced for homicide in a particular year when the actual crime may have been commited in a previous year, this would throw my correlation numbers off.

As you can see based on the scatter plot my hypothesis of the correlation being negative moderate turned out to be wrong. The correlation ended up being positive weak. Since it was positive weak it shows there is in fact a small correlation between the population of people in jail and the amount of people being sentenced to prison for homicide. However, given the number of biases involved it would be difficult to state any conclusion with accuracy. Therefore the amount of people sentenced to homicide doesn't decrease in years when population in jails are high. This can also be shown on my graphs. The population in jails in Canada increases every year while the amount of people sentenced to prison for homicide fluctuates. My statement would be true if the bar graph showed a steady decrease.
 * Conclusion**
