Data Update1

Hello and welcome to my blog post on my idea for my Final Data Report.

I will be answering the four questions provided now.


1. What dataset will you use for your final report? (title of your dataset, include a link to it and claim it at the URL above).

The data set I will be using is the one titled "Number, rate, and percentage changes in rates of homicide victims" from the Statistics Canada page.  

2. Describe the dataset. What kind of data does it contain?

This dataset contains information regarding the number of homicide victims per year, rate per 100,000 population, and yearly percent changes across a ten year span between 2009 and 2019. As well, it provides a 10 year comparison of the percentage change in homicide rates.  

3. Is there anything about your data that you don’t understand? (i.e. what a column heading means). How will you find this out?

Something about my data I don't fully understand is why every year has a "percent change in homicide rates, 10 year comparison" category. As I've marked my data to show me data from 2009 to 2019, would not only 2019 have data? I hope to figure this out by fiddling with my data more and draw connections between data points that will hopefully clear things up.

4. What are some questions you hope to answer with your data? List at least three. (you don’t need the answers at this point)

  • "Comparing the numbers of Canada for the years 2009 and 2019 specifically, is there an increase or decrease in the number of homicide victims? How does this relate to the rate per 100,000 population?"
  • "Which province and/or territory had the highest number of homicide victims? In which year did this happen? What was the rate per 100,000 population?"
  • "Which province and/or territory had the highest rate per 100,000 population number? What was the year it occurred in? What was the actual number of homicide victims that year?"

    Hi Coco,

    I think it's great that you've found a data set that calculates the rate for you, instead of you having to do that calculation yourself. I'm a bit confused about your 2nd and 3rd questions. Are they not the same question?

    Hello Coco,

    I think the questions you posed in question four will be great for the data visualization. They are perfect for graphing and have a lot of potential to reveal interesting facts. I am a bit confused about your method to understand the "10 year comparison" category though. It's a bit vague.

    Hey Coco,

    I like the start of your analysis with this data, the questions are intriguing and I feel like they could lead to more questions down the line when you start to work on the visualizations.

    As to some issues, the question about "Highest rate per 100,000." Although with context it makes sense as to what rate you are referring to, it is still a little confusing at first glance.

Data Update 3

 Hello and welcome to my third Data Update. Before we begin, I would like to address Chad's feedback. As per his feedback, I have broadened my search to the top ten major metropolitan areas by population instead of limiting myself solely to those with a population above 1 million. With these new data points to consider, Toronto was not the only major metropolitan area to see an increased rate. However, Ontario in general had a higher rate compared to the other provinces so I find that it's just as important and relevant. I would also like to point out that although, per the data, Quebec City is considered the metropolitan area with the highest rate change, it is an outlier with 2 homicides in 2009 and 5 in 2019 and therefore excluded from the final data. Chart Unanswered Question Not including homicide, is there an increased crime rate in these metropolitan areas and, if so, what type of crime has there been an influx of? How would you get the data? I would search Statistics...

Data Visualization Analysis - The Most Popular Dog Breeds

Image
The data visualization chart  created by Anjushree B V on the most popular dog breeds does a decent job at explaining and displaying the data. It displays an easy to understand list of the top dog breeds and colour coordinates the dogs to the circular line graph.  The data visualization chart is simple enough that the key only needs two items that help explain the line segments well. Moreover, when you hover over the lines, you will get a box that restates which dog breed's line you're on and when you click a line, it highlights the line segment for the year you are clicking in. However, there are a couple reasons why displaying data this way is not the best. First, turning what would have been a very easy to follow line graph spherical, made it hard to follow the lines even though they are all differently coloured.  As well, pairing that with having the lines abruptly end and restart when a dog breed does not make it into the top ten list for that year is difficult to fo...
