Re-test for Scientific Method

You are a big fan of instagram You are a big fan of instagram. Pretty much every minute of free time you have is spent scrolling through your feed on the gram. You’ve been trying to figure out how to get the most likes on your awesome pictures you post. One day, you post a cute pic of you and your dog and it gets 200 likes! What the heck?!? Scenario 1

Quantitative Observation Qualitative Observation Inference Observation What type of observation did you just make in the first scenario?(One day, you post a cute pic of you and your dog and it gets 200 likes) Quantitative Observation Qualitative Observation Inference Observation

Usually you only get around 100 likes so you think to yourself, how did that picture get so many likes?! You look back on your previous posts and see that this is the first time you have posted a pic with your dog in it and think, it has to be the dog that got me so many likes!

2. When you decided that it must be the dog that got you the likes, which phrase best describes this thought process? Doing an experiment Making an inference Making a conclusion Analyzing data

3. When you found out that you hadn’t posted a picture of your dog before, what type of “knowing” did you use? Media Religion Science Personal Experience

Being the “like” hungry person you are you want to try and figure out how to get that many likes on all your pictures. You think it could have to do with the day that you posted the pic. You decide to conduct an experiment by posting similar pictures (all with your dog) on different days to see if that makes a difference.

You post pictures on Monday, Wednesday, Friday, Saturday, and Sunday You post pictures on Monday, Wednesday, Friday, Saturday, and Sunday. You wait 24 hours from the time each picture is posted and then record the number of likes.

4. What hypothesis was made for why you think you received the most likes on your picture? The picture receives more likes depending on the time you post it. The picture receives more likes depending on the day you post it. The picture receives more likes depending on the picture itself. The picture receives more likes depending on the number of followers you have.

5. What is the independent variable for this experiment? The type of picture. The time of day the picture was posted. The day of the week the picture was posted. The number of “likes” the picture receives.

6. Which of the following was NOT a controlled variable (constant) for the experiment? The number of followers you have before you post the pic. The time of day that you post the picture. The type of picture you post. The day of the week you post the picture.

7. Counting the number of “likes” the picture gets would be which of the following? Independent Variable Dependent Variable Controlled Variable Control Group

Results from the experiment Day of the Week Number of “Likes” Monday @ 5:00 P.M. 154 Wednesday @ 5:00 P.M. 140 Friday @ 5:00 P.M. 178 Saturday @ 5:00 P.M. 195 Sunday @ 5:00 P.M. 198

8. Which type of graph would be the best graph to use for this specific data? Line Graph Bar Graph Pie Chart Data Table

9. From looking at the data, which claim would be accurate? The day of the week you post a picture, doesn’t affect the number of “likes” you receive. Posting a picture at the beginning of the week seems to get the most “likes”. The time of day you post a picture affects how many “likes” the picture gets. You receive the most “likes” on pictures you post on the weekend.

10. Would this experiment be a “fair test”? Yes, because data was collected. Yes, because everyone uses instagram. No, because there were no chemical reactions involved. No, because not enough trials were repeated.
