Box Plots confusing you?

Here’s a simple way to remember how they work.

A box plot is based on five important values:

• Minimum
• Lower Quartile (Q1)
• Median (Q2)
• Upper Quartile (Q3)
• Maximum

Quick Tip:
The box represents the middle 50% of the data.
The line inside the box is the median.
The whiskers help show the spread toward the minimum and maximum.

Save this reel for Statistics revision or share it with a student who finds box plots difficult.

Histograms vs Bar Charts — what’s the difference?

Students often confuse these two graphs, but the key difference is the type of data being shown.

Bar Charts
• Used for categorical or discrete data
• Bars usually have gaps
• Bar height shows frequency

Histograms
• Used for continuous numerical data
• Bars touch each other
• Area represents frequency

Quick Tip:
Bar Chart = Categories
Histogram = Continuous Data

At iTutorzz, our 1-on-1 Maths and Statistics tutoring helps students understand difficult concepts, improve problem-solving skills and prepare confidently for GCSE, IGCSE and A Level exams.

Still mixing up mitosis and meiosis?

You’re not alone — this is one of those Biology topics that can look similar at first, but the differences are important.

Mitosis:
Produces 2 identical cells.
Used for growth and repair.
Keeps the same chromosome number.

Meiosis:
Produces 4 genetically different cells.
Used to make gametes.
Halves the chromosome number.

At iTutorzz, our 1-on-1 Biology tutoring helps students understand key concepts clearly, practise with confidence, and prepare effectively for exams.

With helpful features like Lessons Tracking, Tutor-Student Chat, Google Calendar Sync, and an Interactive Whiteboard, learning stays organised and interactive.

Quadratic equations are much easier when you know the method.

For factorising questions, remember:

Find two numbers → factorise → set each bracket to zero → solve

In this example:

x² + 5x + 6 = 0
becomes
(x + 2)(x + 3) = 0

Final answer:

x = -2 or x = -3

Save this for your next Maths test.

Struggling with simultaneous equations?

Once you know the method, they become much easier:

1. Add or subtract the equations to eliminate one variable
2. Solve for the remaining variable
3. Substitute back to find the second value
4. Check your answer in both original equations

In this example:

x + y = 10
x − y = 2

So the solution is:

x = 6, y = 4

Save this post for your Maths revision and practise the steps until they feel automatic.
