Let us know what you come up with.
mode 5, median 9 and mean 10.5?
mode = 5 <~~yes
median = there is no middle number in the series when you put them in ascending order; therefore, you must find the mean of the two in the center.
mean = add up the 10 numbers and then divide by 10
To find the mode, median, and mean of a set of numbers, follow these steps:
Step 1: Sort the numbers in ascending order: 5, 5, 5, 7, 11, 13, 13, 16, 18, 19.
Step 2: Find the Mode:
- The mode is the number that appears most frequently in the data set.
- In this case, the number 5 appears three times, which is more than any other number.
- Therefore, the mode is 5.
Step 3: Find the Median:
- The median is the middle value in the data set.
- If there are an odd number of values, the median is the middle number.
- If there are an even number of values, the median is the average of the two middle numbers.
- In this case, there are 10 values, so the median is the average of the two middle numbers: 7 and 11.
- The average of 7 and 11 is (7 + 11) / 2 = 18 / 2 = 9.
- Therefore, the median is 9.
Step 4: Find the Mean:
- The mean (or average) is the sum of all the values divided by the total number of values.
- In this case, the sum of the 10 values is 5 + 5 + 5 + 7 + 11 + 13 + 13 + 16 + 18 + 19 = 112.
- The total number of values is 10.
- Therefore, the mean is 112 / 10 = 11.2.
So, the mode is 5, the median is 9, and the mean is 11.2.
