6 tips to reduce stress of staff.
1) If you ask to meet with staff member, let them know why.
2) Don't address an issue you have with one person with the whole staff.
3) Praise a lot more than you critique
4) Fewer meetings
5) More encouragement/support
6) Encourage self care

In my 32 years as a chief meteorologist in Buffalo television, I’ve stayed away from giving advice on school closings, even when my youngest daughter used to lobby me. This time around, it would be inconceivable to me for schools to be open on Friday. Just too dangerous. Period.

Teachers don't leave because it's hard. Teachers are some of the hardest working professionals I know. They leave because the expectations become more unrealistic every year.

This is Auggie. Bad news: He went to fetch a ball and saw some other dog beat him to it. Good news: They just became best friends. 12/10 for both

Effective teachers don't focus so much on rules, but on routines, procedures and expectations. If you focus on rules, you will spend most of the year enforcing them. But if you focus on routines, procedures, and expectations, you rarely have to defer back to the rules.

I’m looking for some help for one of my Statistics students- she’s collecting data for her capstone project and was hoping for many, many responses to her survey about Covid-19. If you have a moment to help we would both appreciate it! Thanks 😊

AP Exam Tip: Know how to interpret a P-value. “Assuming the null is true, the P-value is the probability of getting the observed result or more extreme, purely by chance.” #apstats #MTBoS #statschat #holygrail

[Math Medic (artist formerly known as Stats Medic) @TheStatsMedic]

AP Exam Tip: Know how to read computer regression output. Do you know which values are the slope and y-intercept? #apstats #MTBoS #statschat

This GIF is RAD,

It shows radian, radian is the standard unit of angular measure, used in many areas of mathematics.

AP Exam Tip: When interpreting a confidence interval, always use the word confident (not probability) and be sure to refer to the population parameter and not the sample statistic. #apstats #MTBoS #statschat

[Math Medic (artist formerly known as Stats Medic) @TheStatsMedic]

AP Exam Tip: A good sample design or increasing the sample size does not make your estimate more accurate. It makes your estimate more precise. #apstats #MTBoS #statschat

[Math Medic (artist formerly known as Stats Medic) @TheStatsMedic]

AP Exam Tip: When interpreting slope and y-intercept for a regression equation, be sure to use the word “predicted” or “estimated” in front of the y-variable. #apstats #MTBoS #statschat #yhat

[Math Medic (artist formerly known as Stats Medic) @TheStatsMedic]

AP Exam Tip: When asked to compare two distributions, be sure to compare shape, center, and variability in the context of problem. Don’t simply list. Use words like “greater than, less than, similar to”. #apstats #MTBoS #statschat #SOCV
