Step 1: Background Information on Snapchat
Step 2: Making a Plan
1.Which gender uses 'Snapchat' more
2.Which nationality uses 'Snapchat' more
3.Do people receive or send more 'Snaps'
4.Are there any connections between best friends and if so does having a girl/boy friend have an affect on it.
Then we had to decided what our target audience would be, we chose 8th graders at the school that I go to since it would be the easiest group to ask and it would also allow there to be many nationalities since it is a international school. We decided to make a survey using Google Docs which we did so that both of us could work collaboratively once we were at home. We also decided to use a sample and not a census of 8th students at the school I go to since some people will always be sick and it would have taken to long to do so.
To sum it all up:
Target audience : Grade 8 at B.I.S
Data gathering tool: Google Docs
Census or sample: Sample (samples are always more realistic but not as precise)
Step 3: Making the Survey
Decide what questions you are going to ask, we asked for name, age, snaps sent and received (and how this can be found), there 3 best friends and their relationship to each of these friends.
2. Stopping spam
After we asked several people to do the survey over Facebook, this went terribly wrong since we got several answers, even tough it did contain the asked information, were highly inappropriate. Some of the cleaner ones were "124 nudes and counting" or "43 potatoes" these made us take extra time to delete any swear/unnecessary words. After we sent it out on Facebook we decided to stop this from wasting our time, so we added rules to the survey. This made it possible to ONLY have whole numbers as an input. In the below pictures you should find a picture with the settings that I used to do this.
3. Confidentiality is key
In this Instructable we were not able to add any information about who is dating who in my school or the best friends list since this would be against some law and I personally would away getting sued. So remember when doing your survey DON'T ask for personal information ONLY if you have permission to use it.

Step 4: Carrying Out the Survey
Step 5: Data Visualization
Step 1.Central Tendencies of Data (averages)
First of all we copied all of the information we had from the Google docs into a plotly spreadsheet. To do most of our charts we had to use averages, the mean is the most commonly and widely used type of average. We averaged the mean of Snaps sent and received per nationality (picture 3) afterwards we copied this information into a plotly spread sheet.
Step 2. Data Visualization
Now we get to the fun stuff, we will be making 2 graphs a heat map for nationality and a scatter diagram for gender. Lets start with the heat map, we went to our spreadsheet with the mean sent and received from each nationality. Then select as shown in picture 4 heat map and in picture 5 to select the nationality column as y axis and the mean sent and received as the z. Then you should get something like in picture 6. These colors all look quite the same so lets change the colors. I did this by clicking on traces and then style. I used the rainbow gradient since it looked the best and you could see the biggest difference between the smaller numbers. The final graph is visible in picture 7

Step 6: Data Visualization Continued
Now we will make the scatter graph of snaps sent and received depending on gender. First of all open the spreadsheet as shown in picture 1. Then select scatter plot. Then as shown in image 3 chose snaps sent as the x (or the y it does not matter) and snaps received as the y. Then click on Group by and select the gender as G. Now click on scatter plot and your graph should look like the one in picture 4.
Step 4. Line of best fit
Nowwe are going to add a line of best fit we do this by clicking on fit data button (as visible in image 5) and then "Add fit to this trace" then just use the default equations and the line should pop up and look like the one in image 6.
Step 5. Titles
To finish this graph off lets add some labels and titles. After you are done it should look like picture 7.

Step 7: Summerizing
1.Girls send and receive more than boys no matter how long they have had the application
2.Both genders receive more than they send
3.Boys that have girlfriends receive more than they send
4.Barley anyone 'snaped' with their family members
5. Americans and Romanians send and receive the most 'snaps'
Areas of improvement
1.Ask more people
3.Ask people in other grade levels
4.Put the survey on social media.
5.Make some cool charts with the best friends (e.g. friend web)
