Answer:
Median is 6
standard deviation is 2.39
Step-by-step explanation:
the median is the mid number in the data set
The median formula is {(n + 1) ÷ 2}th, where “n” is the number of items in the set and “th” just means the (n)th number.
There are 51 data points in this set (n = 51)
so 51 / 2 = 25.5, the. number in the 25th slot is our median
3, 3, 3, 3, 4, 4, 4, 4, 4, 5, 5, 5, 5, 5, 5, 5, 6, 6, 6, 6, 6, 6, 6, 6,<u> 6</u>, 6, 7, 7, 7, 7, 7, 7, 8, 8, 8, 8, 8, 9, 9, 9, 9, 10, 10, 10, 10, 10, 11, 11, 11, 11, 11
the standard deviation is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.
The four?
Of course there are an infinite number of rationals between any two different real numbers, as well as an even bigger infinite number of irrationals.
The average will be between the numbers:
That's a lot of work to get a number in between. We can just see
is between the two numbers.
The mediant, or freshman addition, will always be in between:
2/5=.4 and 5/6 is about .83, so
is in between as is .7, .41, .530940394 and as many rationals as we care to generate.
To get irrationals we could just add a teeny irrational to the ones we just generated, like
We could just change that denominator a bit and get as many as we like.
But let's get some square roots. The geometric mean will be between
That's the tangent from one of trig's biggest cliches, but I digress. It's in between.
While we're on trig cliches,
is in between as well.
Keeping with the trig theme, also in between are
and
the angles associated with the some of the above trig function values.
We could obviously go on as long as we cared to.
