u need to put them in order from least to greatest(25,32,32,33,34,35,37,40,42,46) then the mean is 35.6
the median is 34.5
the mode is 32
the mid-range is 21
To find the mean, median, mode, and mid-range of a set of data, follow these steps:
1. Mean:
To find the mean, add up all the numbers in the dataset and then divide the sum by the total number of values.
For your dataset:
37 + 35 + 32 + 34 + 40 + 46 + 25 + 32 + 42 + 33 = 356
Now, divide it by the total number of values (10 in this case):
356 / 10 = 35.6
Therefore, the mean is 35.6.
2. Median:
To find the median, arrange the numbers in ascending order and then locate the middle value. If there are two middle values, take their average.
Arranging the numbers in ascending order:
25, 32, 32, 33, 34, 35, 37, 40, 42, 46
The median value is the middle value, which is 34 in this case. Hence, the median is 34.
3. Mode:
To find the mode, identify the number(s) that appear most frequently in the dataset.
In your dataset, there is no number that appears more than once. Therefore, there is no mode.
4. Mid-range:
The mid-range is the average of the smallest and largest values in the dataset.
The smallest value is 25, and the largest value is 46.
Mid-range = (25 + 46) / 2 = 71 / 2 = 35.5
Thus, the mid-range is 35.5.
In summary, for your dataset:
Mean = 35.6
Median = 34
Mode = None (no mode)
Mid-range = 35.5
