a pipet delivers 9.04,9.02,9.08,9.06 ml in consecutive trials.find the mean volume and the average deviation from the mean

9.04

9.02
9.08
9.06
Find the mean which I will call 9.04 but you need to calculate it. 9.04 is an estimate only.
Then 9.04-9.04 = 0
9.02-9.04 = 0.02 (disregard the signs)
9.08-9.04 = 0.04
9.06-9.04 = 0.02
Now find the mean of those differences. That will be (0.00 + 0.02 + 0.04 + 0.02))/4 = ?0.065 and round to the correct number of significant figures.

Well, well, well! Looks like we have a pipetting problem on our hands!

To find the mean volume, we simply add up all the values and divide by the number of trials. Let's do that math:
(9.04 + 9.02 + 9.08 + 9.06) / 4 = 9.05 ml

The mean volume is 9.05 ml. Voila!

Now, let's calculate the average deviation from the mean. This is the average difference between each value and the mean. Let's take it one step at a time:

First, we subtract the mean from each value:

9.04 - 9.05 = -0.01
9.02 - 9.05 = -0.03
9.08 - 9.05 = 0.03
9.06 - 9.05 = 0.01

Now, we take the absolute values of these differences (because we don't want negative values throwing off our calculations):

|-0.01| = 0.01
|-0.03| = 0.03
|0.03| = 0.03
|0.01| = 0.01

Finally, we add up these absolute differences and divide by the number of trials:

(0.01 + 0.03 + 0.03 + 0.01) / 4 = 0.02 ml

So, the average deviation from the mean is 0.02 ml.

Remember: Pipetting might be a serious business, but it's always good to laugh along the way!

To find the mean volume, you need to calculate the average of the volumes obtained in the consecutive trials.

1. Add up the volumes from all the trials: 9.04 + 9.02 + 9.08 + 9.06 = 36.2 ml.
2. Divide the sum by the total number of trials (in this case, 4): 36.2 ml / 4 = 9.05 ml.

Therefore, the mean volume is 9.05 ml.

To calculate the average deviation from the mean, follow these steps:

1. Subtract the mean volume from each individual volume measurement to calculate the deviation for each trial:

- For the first trial: 9.04 ml - 9.05 ml = -0.01 ml
- For the second trial: 9.02 ml - 9.05 ml = -0.03 ml
- For the third trial: 9.08 ml - 9.05 ml = 0.03 ml
- For the fourth trial: 9.06 ml - 9.05 ml = 0.01 ml

2. Find the absolute value of each deviation.
- Absolute value of -0.01 ml = 0.01 ml
- Absolute value of -0.03 ml = 0.03 ml
- Absolute value of 0.03 ml = 0.03 ml
- Absolute value of 0.01 ml = 0.01 ml

3. Add up the absolute deviations:
0.01 + 0.03 + 0.03 + 0.01 = 0.08 ml.

4. Divide the sum of the absolute deviations by the total number of trials (in this case, 4) to find the average deviation:
0.08 ml / 4 = 0.02 ml.

Therefore, the average deviation from the mean is 0.02 ml.

To find the mean volume, you need to add up the individual volumes and then divide the sum by the total number of trials.

Mean Volume:
1. Add up the individual volumes: 9.04 ml + 9.02 ml + 9.08 ml + 9.06 ml = 36.2 ml
2. Divide the sum by the total number of trials: 36.2 ml / 4 trials = 9.05 ml

Therefore, the mean volume is 9.05 ml.

To find the average deviation from the mean, you need to calculate the absolute difference between each individual volume and the mean volume, then find the average of these differences.

Average Deviation from the Mean:
1. Calculate the difference between each individual volume and the mean volume:
- Difference for the first trial: |9.04 ml - 9.05 ml| = 0.01 ml
- Difference for the second trial: |9.02 ml - 9.05 ml| = 0.03 ml
- Difference for the third trial: |9.08 ml - 9.05 ml| = 0.03 ml
- Difference for the fourth trial: |9.06 ml - 9.05 ml| = 0.01 ml

2. Find the average of these differences:
- Average deviation = (0.01 ml + 0.03 ml + 0.03 ml + 0.01 ml) / 4 trials
- Average deviation = 0.08 ml / 4 trials
- Average deviation = 0.02 ml

Therefore, the average deviation from the mean is 0.02 ml.
