Sheep variability of data quiz, part two
To calculate the lower quartile (Q1):
1. Arrange the data in order from smallest to largest: 20,22,25,28,29,30,32,33,34
2. Calculate the median (middle value) of the lower half of the data set. In this case, the lower half is: 20, 22, 25, 28. Therefore, the median is (22+25)/2 = 23.5.
This value is the lower quartile (Q1).
To calculate the upper quartile (Q3):
1. Arrange the data in order from smallest to largest: 20,22,25,28,29,30,32,33,34
2. Calculate the median (middle value) of the upper half of the data set. In this case, the upper half is: 30, 32, 33, 34. Therefore, the median is (32+33)/2 = 32.5.
This value is the upper quartile (Q3).
To calculate the interquartile range (IQR):
1. IQR = Q3 - Q1
2. In this case, IQR = 32.5 - 23.5 = 9.

teach me long division
Sure, I can teach you how to do long division!
Long division is a method of dividing two numbers in which we write the dividend (the number being divided) on the top and the divisor (the number dividing the dividend) on the left-hand side. Then, we proceed step by step to divide the digits of the dividend by the divisor until we get the quotient (the result of the division) and the remainder (any number that does not fit evenly into the division).
Here are the basic steps to perform long division:
Step 1: Write the dividend and divisor in the correct format.
Example: Divide 453 by 3
--------
3 | 453
Step 2: Divide the first digit of the dividend (4) by the divisor (3) and write the quotient (how many times the divisor fits into the digit) above the dividend.
Example:
1
--------
3 | 453
Step 3: Multiply the quotient by the divisor and write the result under the first digit of the dividend.
Example:
1
--------
3 | 453
3
Step 4: Subtract the product from the first digit of the dividend (4 - 3 = 1) and bring down the next digit (5) to the right of the result.
Example:
1
--------
3 | 453
3
---
1
Step 5: Divide the new value (15) by the divisor (3) and write the quotient (5) above the last digit.
Example:
15
--
3 | 453
3
---
15
15
--
0
Step 6: Multiply the quotient (5) by the divisor (3) and write the result under the last digit of the current remainder (0).
Example:
15
--
3 | 453
3
---
15
15
--
0
---
3
Step 7: Subtract the product from the remainder (0 - 0) and check if any digits remain. If not, the quotient is complete.
Example:
15
--
3 | 453
3
---
15
15
--
0
---
3
In this example, the quotient is 151, and the remainder is 0. So, 453 divided by 3 is 151.

how to multiply big numbers
Multiplying big numbers can seem daunting, but there are techniques that you can use to make the process easier. Here's a step-by-step guide on how to multiply large numbers:
Step 1: Write the numbers vertically, one digit per column, so that the digits match in their corresponding columns.
For example, if you are multiplying 346 and 25, you would write:
```
346
x 25
```
Step 2: Begin by multiplying the digits in the ones column (the right-most column) of the second number (5 in this case) by each digit in the first number (6, 4, and 3). Write each product below its corresponding digit in the ones column.
```
346
x 25
-----
30
20
5
```
Step 3: Move to the tens column of the second number (the column to the left of the ones column) and repeat step 2, but add a 0 to the right of each product. Then, add the products together.
```
346
x 25
-----
30
20
5 0
+---------
8650
```
Step 4: Check the answer to make sure it makes sense.
In this case, you could check by mentally dividing 8650 by 25 to see if it approximately equals 346.
And that's it! These are the basic steps for multiplying big numbers. With practice, you'll become more comfortable with this process and be able to apply it to even larger numbers.
