find the mean, median and mode of the quiz scores 74, 85, 89, 93, 85 & 90.

For the mean, add these numbers together and divide by 6.

For the median, arrange the numbers in order.

74, 85, 85, 89, 90, 93

The middle number is the median. In this case -- it's half way betwen 85 and 89 -- 87.

This site explains all three of these terms.

thank u

for the mean i got 86, median 89 and mode 85

I already told you the median.

The other two are correct.

With a mean of 72, and SD of 10 of High temprature:

Temprature of 93 is how many SD above mean?
Temprature of 54 is how many SD below mean?
Show your calculations.

To find the mean, median, and mode of the given quiz scores, follow these steps:

1. Addition: Add up all the given quiz scores.
74 + 85 + 89 + 93 + 85 + 90 = 516

2. Mean: Divide the sum of the scores by the number of data points.
Mean = Sum of all scores / Number of data points
Mean = 516 / 6 = 86

The mean of the quiz scores is 86.

3. Median: Arrange the scores in ascending order and find the middle value.
74, 85, 85, 89, 90, 93

Since there are six data points, the median will be the average of the middle two values.
Median = (85 + 89)/2 = 87

The median of the quiz scores is 87.

4. Mode: Identify the data point(s) that appear most frequently.
In this case, the mode is 85, as it occurs twice.

The mode of the quiz scores is 85.

So, the mean is 86, the median is 87, and the mode is 85.
