hello, i have an assignment that I was wondering if someone could check my answers. Thank you! :)
1. Which of the scatter plots above shows a negative trend?
I - No Trend
II - Negative Trend
III - Positive Trend
My answer - A) Graph II
2. The scatter plot below shows the population of a village (P) over time (t). Describe the relationship between the population of the village over time.
Graph:
P - 1000 - 5000
t - 0 - 10
Population stay around 3000.
My answer - A) The population remains roughly the same over time.
3. Complete the sentence below.
Scatter plots are used to look for a pattern of association, or trend, between ?
My answer - two sets of values
Oops, for #3, meant to say "My answer - B) two sets of values".

merlana is 100% correct 3/3! Your really smart! thanks!!!
Your answers are correct!
1. Graph II shows a negative trend in the scatter plot.
2. The population of the village remains roughly the same over time.
3. Scatter plots are used to look for a pattern of association, or trend, between two sets of values.
Well done!
1. To determine which scatter plot shows a negative trend, you need to analyze the overall direction of the points. A negative trend means that as one variable increases, the other decreases.
To examine this, you can look at the scatter plot graphs I, II, and III. Analyze the relationship between the x-axis and y-axis values in each graph:
- Graph I shows no identifiable trend. The points seem to be scattered randomly and do not follow any specific pattern.
- Graph II displays a negative trend. As the x-axis values increase, the corresponding y-axis values decrease.
- Graph III demonstrates a positive trend. As the x-axis values increase, the corresponding y-axis values also increase.
Considering this information, your answer (A) Graph II is correct.
2. To describe the relationship between the population of the village over time based on the scatter plot, analyze the position of the points along the x-axis (time) and y-axis (population).
Looking at the given data, you can observe that the population (P) remains around 3000 at different time (t) intervals. This indicates that regardless of the time passing, the population of the village remains relatively stable or constant.
Therefore, your answer (A) The population remains roughly the same over time is correct.
3. To complete the sentence, you need to identify what scatter plots are used to look for a pattern of association or trend between.
Scatter plots are used to look for a pattern of association, or trend, between two sets of values. These two sets of values are represented by the x-axis and y-axis coordinates on a scatter plot. By plotting the data points and analyzing their distribution, scatter plots can help identify any relationships, correlations, or trends between these two variables.
Hence, your answer - two sets of values is correct.
