Write positive, negative, or no correlation for each situation.
1.rate of drainage and water level remaining after 5 mins
2.time spent swimming and total calories used
3.number of holidays and number of honor students
#1. since the water level is dropping at a constant rate, I'd say negative
what do you think on the others?
okay, the second one i think positive and the third i think no correlation
I agree
thank you!!
To determine the correlation between two variables, you need to analyze the relationship between them. A positive correlation means that as one variable increases, the other variable also tends to increase. A negative correlation means that as one variable increases, the other variable tends to decrease. No correlation means that there is no consistent relationship between the two variables.
1. Rate of drainage and water level remaining after 5 minutes: Negative correlation. As the rate of drainage increases, the water level remaining after 5 minutes will likely decrease. To determine the correlation, you can collect data on different drainage rates and measure the corresponding water levels after 5 minutes. Plot the data points on a graph and observe the general trend.
2. Time spent swimming and total calories used: Positive correlation. As the time spent swimming increases, the total calories used will also increase. To determine the correlation, you can keep track of the time spent swimming and calculate the corresponding total calories burned. Plot the data points on a graph and observe the general trend.
3. Number of holidays and number of honor students: No correlation. The number of holidays and the number of honor students are likely unrelated. To determine if there is any correlation, you can obtain data on the number of holidays and the number of honor students over a specific period. Plot the data points on a graph and observe if there is any consistent pattern or trend. If the data points appear scattered with no apparent relationship, then there is likely no correlation.
