With very little I know, calculating standard deviation
1. Count of Math Scores
:
Use the COUNT function to find the total number of math scores.
Example formula: =COUNT(A2:A100) (Assuming your math scores are in column A from rows 2 to 100).
2. Count of Math Scores (n-1):
Simply subtract 1 from the count you calculated.
Example formula: =COUNT(A2:A100) - 1.
3. Mean (x̄):
Use the AVERAGE function to find the mean of the math scores.
Example formula: =AVERAGE(A2:A100).
4. Σ(x - x̄)²:
You will need to calculate the squared differences. In a new column (let's say column B), use the formula:
=(A2 - $C$1)^2 (assuming C1 contains the mean).
Drag this formula down to apply it to all scores.
Then use the SUM function to sum the squared differences.
Example formula: =SUM(B2:B100).
5. Σ(x - x̄)² / (n-1):
Divide the sum of squared differences by n−1n−1.
Example formula: =SUM(B2:B100) / (COUNT(A2:A100) - 1).
6. Square Root of Σ(x - x̄)² / (n-1):
Use the SQRT function to find the square root.
Example formula: =SQRT(SUM(B2:B100) / (COUNT(A2:A100) - 1)).
7. Standard Deviation Function =STDEV.S:
You can use Excel's built-in standard deviation function as a check.
Example formula: =STDEV.S(A2:A100).

Network+ N10-009 - Course Pacing

I had a similar issue when teaching Network+ on a 5-day schedule. What worked for me was focusing on core labs during class and assigning the rest as homework. For example, in my Security+ course, we covered essential hands-on labs in class and left around 50% for self-study. This helped us stay within the 5-day window without overwhelming the students with too many labs during sessions.Hello CIN Team,
Firstly, thank you Stephen and Don for a fantastic TTT series. I really enjoyed it.
I finally got my hands on the instructor resources for this new version of Network+ and I was looking at the pacing guide. I'm interested in the 5 day pacing which is what my academy is delivering courses to. I noticed that the 5 day sheet in the pacing guide has you doing 20 hour per day for 5 days
Thanks
Rasheed
Hopefully, a refined pacing guide comes out, but this approach might help in the meantime!

Hello CIN Team,

I'm interested in the 5 day pacing which is what my academy is delivering courses to. I noticed that the 5 day sheet in the pacing guide has you doing 20 hour per day for 5 days I also noted that there were around 160 short labs for the learners to do which aren't part of the pacing. I thought the latest Sec+ (701) planner did a pretty good job of breaking things out into what to do in class and how to pace over 5 days. Does anyone have any recommendation on teaching over 5 days or is there a better planner in the works somewhere ?
Thanks

Songs I Created
Can you believe a left-brainer like me actually created music? My Suno screen name is Zeus Lives in California.With the prompt “A synthesizer-driven song to go with scuba diving video in the Caribbean. Slow, mysterious and refreshing. Mix in water sounds,” I created at two instrumentals, Vacation (Time to Turn Off Your Phone) at https://suno.com/song/cac22c27-fd70-4ec8-a5fc-92c7003ee78c and Dive In (You Know You Want to be Here) at https://suno.com/song/365ee095-78bf-4068-8a15-bf45e69a9d93.
With the prompt “A bright and slow techno pop song about viewing aurora borealis alone at midnight. Spatial, mysterious and galactic,” I created two instrumentals, Bright Midnight Lights, at https://suno.com/song/a0e3d033-1aa3-4ab4-9d72-1a98439accb6 and Midnight Lights at My Piano, at https://suno.com/song/1532f546-36c8-4acc-b433-71e2520df0fc.
